Paris–Brest–Paris 2027
70 Hints, Tips & Pieces of Advice
Paris–Brest–Paris is much more than simply riding 1,250 kilometres. Successful riders repeatedly emphasise preparation, pacing, organisation, sleep, food, comfort and the ability to adapt when things do not go according to plan.
The following advice brings together recurring lessons from experienced PBP riders, ride reports, blogs and official PBP guidance.
BEFORE PBP
1. Build your 2027 qualifiers into your PBP preparation rather than regarding them as paperwork.
You must complete BRMs of at least 200, 300, 400 and 600 km in 2027. Use them to test your actual PBP bicycle, clothing, lights, feeding and sleeping arrangements.
2. Do at least one significant BRM in 2026 if possible.
It isn't necessary to qualify, but your longest qualifying BRM ridden between 1 November 2025 and 31 October 2026 determines how early you can pre-register and therefore improves your choice of starting wave. A 1000 km/RM1200+ allows pre-registration from 16 January 2027; 600 km from 30 January; 400 km from 13 February; 300 km from 27 February; and 200 km from 13 March.
3. Train for accumulated fatigue, not just distance.
A 600 km brevet proves that you can ride 600 km. It doesn't entirely prepare you for another 600 km while sleep deprived. Multi-day fatigue changes your judgement, motivation, appetite and bike handling, and minor discomforts become major ones.
4. Include hills in your preparation.
PBP isn't mountainous, but it is relentlessly rolling. The official figure is currently around 11,000 m of climbing. Riders from flat areas repeatedly report that the constant climbing eventually becomes significant.
5. Do some long rides at night.
Don't make PBP your first experience of riding through 2–5 a.m. Learn how your body responds to sleepiness, cold, darkness and eating in the middle of the night.
6. Choose your start wave according to how you actually ride.
For 2027, solo riders can select 80-hour Sunday starts, normal 90-hour Sunday starts, or 84-hour Monday-morning starts, subject to availability. The 84-hour start appeals to some experienced riders because you begin after a normal night's sleep and encounter fewer riders; the 90-hour start gives you six additional hours but immediately sends you into an overnight ride. Neither is intrinsically superior.
7. Book Rambouillet-area accommodation early.
Previous rider reports describe nearby accommodation disappearing a very long time before the event. Ideally choose somewhere that accepts bicycles in rooms or has genuinely secure bicycle storage.
8. Arrive early enough to relax rather than simply survive the logistics.
For 2027 you must be in Rambouillet the day before your start to collect equipment, and riders should be present at least one hour before their actual departure.
9. Eat and sleep properly before the start.
Don't ruin six months of preparation by spending the preceding day sightseeing around Paris, standing in queues and getting five hours' sleep.
BIKE & KIT
10. Use two bottles unless you have a proven alternative.
A previous rider considered taking only one to save weight and was strongly advised against it. At PBP, flexibility over where you refill is far more valuable than saving a few hundred grams.
11. Don't underestimate August nights.
Previous PBPs have ranged from intense heat to very cold nights and prolonged rain. One experienced rider reported temperatures around 3–7°C during previous editions despite pleasant daytime conditions.
12. Take a genuinely useful waterproof.
The 2027 route reaches western Brittany, so assume that rain and Atlantic weather are possible even if the long-range forecast looks excellent.
13. Protect hands and feet from wet and cold.
Riders understandably focus on jackets, but cold wet fingers can make braking, shifting and opening food difficult; cold feet can become miserable after hours.
14. Prioritise comfort over marginal speed.
The official PBP guidance recommends a road or gravel bike with geometry appropriate to you and says to prioritise comfort over performance.
15. Consider wider road tyres.
The 2027 course is asphalt, and the organisers specifically suggest comfortable road tyres and say that if your bike accepts 28 mm or wider, don't hesitate to use them for additional comfort.
16. Use the exact saddle, shorts and position you've proved over long rides.
A tiny saddle problem at 200 km can become an enormous problem at 900 km. The same applies to hand numbness, shoes, cleats, knee position and handlebar reach.
17. Do not make last-minute bicycle changes.
One 2019 rider fitted an untested route-sheet holder just before PBP and discovered during the event that it interfered with his hand position. The lesson is simple: important equipment should be tested under approximately PBP conditions first.
18. Start with an immaculate drivetrain and reliable tyres.
PBP is a poor place to discover that a chain is almost worn out, a freehub occasionally sticks or a tyre has another 500 km left in it.
19. Carry enough repair equipment to solve the common problems yourself.
Sensible basics include spare tubes or appropriate tubeless repair equipment, pump, tyre levers, multitool, zip ties, chain quick-link, rear derailleur hanger and a small amount of tape. Don't take an entire workshop.
20. Have redundancy in your lights.
You are going to ride at night. The official bike inspection concentrates on safety equipment including your helmet, reflective vest and lights.
21. Work out your charging system before France.
GPS, phone and lights create a surprisingly large electricity requirement over 80–90 hours. Decide whether you're using dynamo power, power banks or mains charging and test the complete system on a 400/600.
22. Make everything accessible without emptying the bike.
Food, waterproof, gloves, reflective vest, power bank and basic tools should have predictable locations. At 700 km, organisation is worth far more than saving 150g.
23. Pack lighter than you initially think necessary.
One 2019 rider discovered that his 9.5 kg bike had become an 18.5 kg bike when fully equipped. After a difficult 300 km test he removed unnecessary equipment and added hill training.
24. But don't chase weight at the expense of reliability or comfort.
An additional layer, second bottle or dependable light is worth considerably more than the few hundred grams it costs.
25. Plan on carrying your own equipment in 2027.
At present, the organisers say that bag drops are not planned. Most controls will have catering and accommodation, but not necessarily every service at every control.
FOOD & DRINK
26. Carry enough food for the opening section.
An experienced rider's favourite PBP tip was to stock up before the start so he didn't have to join the huge early food queues. Getting slightly ahead of the main concentration—or “bulge”—of riders can save substantial time later.
27. But don't try to carry three days of food.
Part of PBP is using controls, shops and the extraordinary roadside hospitality. The better strategy is usually enough food to give yourself choices rather than making every food stop compulsory.
28. Eat before you're desperate for food.
On a 1200 km ride, recovering from a serious calorie deficit is much more difficult than preventing one. As fatigue accumulates, appetite can disappear, so use the qualifiers to discover foods you can still tolerate after 400–600 km.
29. Don't rely entirely on sports nutrition.
Many experienced randonneurs increasingly want ordinary food after a day or two: sandwiches, rice, soup, potatoes, pastries, yoghurt, fruit and similar foods. PBP's French controls and roadside stands are part of the experience.
30. Keep drinking—but don't blindly overdrink.
August can be extremely hot. The 2023 edition included very hot conditions and riders reported significant problems with heat. Brittany can equally deliver cold rain and wind.
31. Carry multiple ways of paying.
Card plus some euros in cash gives resilience for village shops, roadside offerings, temporary control facilities or payment-system problems.
CONTROLS & TIME MANAGEMENT
32. Treat controls as potential time traps.
PBP controls deal with hundreds or thousands of cyclists. You may queue to validate your card, eat, use the toilet, shower or sleep. A stop you imagine taking 15 minutes can become 45 minutes or more.
33. Arrive at a control knowing exactly what you need to do.
A useful routine is something like: park bike → card/control → toilet → bottles → food → clothing/batteries → leave. Wandering around deciding what to do is how 20-minute stops become an hour.
34. Keep your control card/brevet, phone and money in exactly the same place throughout the ride.
Never put them down casually on a cafeteria table when exhausted.
35. Remember where you parked your bike.
This sounds ridiculous until you arrive at an enormous school complex containing hundreds of nearly identical bicycles at 3 a.m. One experienced PBP rider specifically mentions losing time simply looking for his bike at controls.
36. Don't obsess over a minute-by-minute spreadsheet.
Planning is useful; believing the plan will survive reality is not. Experienced riders have concluded that detailed predictions of arrival, eating and sleeping times rarely survive weather, queues, fatigue and mechanical problems.
37. Do understand your overall time budget.
Ninety hours sounds enormous because 1,250 km ÷ 90 h is only about 13.3 km/h. But that 90 hours includes sleeping, eating, queues, mechanical problems, toilets and every other minute when the bicycle isn't moving.
38. Build a time cushion—but don't exhaust yourself creating it.
Riding slightly faster than necessary while fresh can create useful sleeping time later. Riding at threshold for six hours to gain 45 minutes is normally a bad trade.
39. The 2027 control timing system is somewhat simpler.
Controls still have opening and closing periods, but the organisers say the previous individual control cut-offs based on each start wave have been removed. Your individual overall limit remains 80, 84 or 90 hours from your start.
SLEEP
40. Find out how little—or how much—sleep you personally need.
There is no universal PBP sleep strategy. One experienced rider argues that 90-hour starters should normally ride through the first night, while a tandem team with six PBP finishes deliberately used the 84-hour morning start and planned three sleep stops. Both approaches worked. The useful lesson is to discover your sleep strategy before PBP.
41. Don't confuse stopping with sleeping.
A planned 2½-hour hotel stop doesn't mean 2½ hours of sleep. Finding the hotel, parking the bike, checking in, eating, washing, changing and preparing to leave can consume most of it.
42. Short, strategically timed sleeps can be extremely effective.
Riders report using control dormitories, hotels, floors, roadside naps and 10–20 minute emergency naps. Learn whether a 15–30-minute nap actually restores you before relying upon it at PBP.
43. Don't regard control dormitories as a last resort.
One rider who initially booked hotels concluded afterwards that control dormitories could be more time-efficient because there was no detour, check-in or journey back to the route. Avoiding their busiest periods is important.
44. When you're dangerously sleepy, sleep.
Trying to “save” 20 minutes while struggling to keep your eyes open is irrational. Find somewhere safe and take the nap.
ON THE ROAD
45. Ride PBP as an endurance event, not as a very long sportive.
The overwhelming theme from successful riders is restraint. The first 200–300 km can feel remarkably easy because you are excited, surrounded by thousands of riders and constantly finding groups. Resist the temptation to ride above your normal all-day pace.
46. GPS is backup as well as navigation.
PBP will be signposted, but the organisers explicitly recommend carrying a GPS with the route downloaded because signs can disappear or be missed.
47. Never simply follow the wheel in front.
Several rider accounts mention navigation mistakes caused by following somebody who was equally lost. Fatigue makes this particularly easy on the return journey.
48. Know roughly where you are going geographically.
You shouldn't need your Garmin to know whether you ought generally to be heading west toward Brest or east toward Rambouillet. A rough mental picture helps catch navigation mistakes early.
49. Don't become dependent on one riding partner.
One veteran's lesson was to become a “free agent”: ride with compatible people while it works, but don't spend 45 minutes waiting because somebody you've known for three hours wants a shower or a long meal.
50. Expect to constantly form and lose groups.
PBP is unusually sociable. You'll ride with French, British, Belgian, German, Japanese, Indian, American and countless other riders for 10 km or 100 km and then probably never see them again.
51. Be particularly careful in large groups during the opening hours.
Thousands of excited riders with different bunch-riding experience, languages and braking habits are sharing public roads. Rider reports regularly mention early crashes and nervous moments.
52. Don't sit on aerobars in a group.
Aerobars are explicitly allowed in 2027, but the organisers recommend not using them while following another rider because you need immediate access to the brakes.
53. Use other riders for shelter sensibly, not desperately.
A good group can save significant energy into a headwind. A group riding 3 km/h above your sustainable pace can destroy your ride. Let it go.
54. Learn a little French.
You certainly don't need fluent French, but bonjour, merci, s'il vous plaît, de l'eau, à manger, où sont les toilettes ?, je voudrais dormir, and a few cycling/mechanical words make the experience easier. Riders regularly report that even rudimentary French noticeably enriches their interaction with locals and other riders.
55. Plan for roadside hospitality.
One thing that appears in almost every PBP account is families and villages offering water, coffee, food and encouragement. It isn't just a convenient source of calories—it is one of the defining experiences of PBP.
56. Acknowledge the spectators.
Wave, smile and say merci. One repeat rider actually made this one of his principal lessons from PBP because of the extraordinary effort local residents make for riders.
57. Be especially nice to the volunteers.
By your third night, everyone is tired—including them. PBP only functions because a huge number of people are helping thousands of exhausted cyclists.
58. Don't treat every bad moment as evidence that you're failing.
Feeling terrible for 30 minutes at 700 km can be followed by feeling remarkably good at 750 km. Food, temperature, daylight, company, caffeine or 20 minutes' sleep can completely change how the ride feels.
59. Have an abandonment plan.
If you DNF, getting yourself back to Rambouillet is principally your responsibility. Know how you would use French trains, carry payment and identification, and don't assume an organiser's broom wagon will collect you.
60. Don't rely on family tracking as precise GPS tracking.
The PBP frame chip records passage at controls; it is not continuous live tracking. Tell anyone following you this beforehand so that a long period without an update doesn't create unnecessary concern.
61. Remember that outside vehicle assistance is tightly controlled.
PBP is self-supported. Vehicle support is prohibited along the route; declared vehicle assistance is only permitted in designated control towns. The organisers have said enforcement of this is a particular priority for 2027.
THE FINAL 300 KM
62. Do not assume Brest means you're virtually finished.
Mentally, 600 km feels like enormous progress; physically, you still have another long-distance event to ride. Experienced riders repeatedly describe the return as a very different ride because fatigue, hand pain, saddle soreness and sleep deprivation have accumulated.
63. Expect a psychological dip somewhere around the middle.
Several reports describe moments when riders seriously contemplated abandoning despite being physically capable of continuing. Eat, drink, cool down or warm up and get some sleep before making an irreversible decision.
64. Break PBP into controls rather than contemplating 1,250 km.
“Rambouillet to Brest and back” is intimidating. “Ride to the next control, eat something and reassess” is manageable. One experienced rider described getting through his preparation and difficulties by taking things “one control at a time.”
65. Expect the final 150–200 km to hurt.
Even experienced repeat finishers describe the final day as one where legs don't initially work, hands hurt and saddle discomfort has accumulated. Interestingly, they also describe the body gradually coming back to life once riding again.
FINALLY – REMEMBER WHY YOU ARE THERE
66. Don't wish the whole thing away.
Riders who have completed multiple editions repeatedly talk less about their finish time afterwards and more about villages, spectators, other randonneurs, bizarre conversations at 3 a.m., food stops and sunrises.
67. Take some photographs.
Not hundreds, and not enough to interfere with riding—but enough. Sleep deprivation means surprisingly large portions of a 90-hour event can become blurred afterwards.
68. Forget about having a perfect PBP.
You will probably encounter at least one of: terrible legs, an upset stomach, rain, heat, a navigation mistake, a mechanical issue, queues, saddle pain, an unexpected sleep, or a control that takes twice as long as expected. Successful PBP riding is largely about absorbing these problems without allowing one problem to become three.
69. Ride your own ride.
This is perhaps the most repeated piece of experienced-randonneur advice. Listen to everyone—including lists like this—but use the qualifying series to discover your pace, your food, your saddle, your clothing, your sleep requirement and your control routine.
70. Above all, leave enough mental space to enjoy PBP.
It is an unusual event: thousands of riders from around 70 countries, riding through French villages where people come out day and night simply to encourage them. Multiple-time finishers describe that atmosphere and local support—not the 1,250 km statistic—as the reason they return.
