300 km brevet training plan

A 300 km brevet usually means riding into the night with a 20-hour limit. It is the first distance where durability, not FTP, decides how the last 100 km feel.

What a 300 km brevet demands

Twelve or more hours of riding expose what a 200 hides: a pace you cannot hold after hour eight, a stomach that refuses another gel, and a contact point that starts to hurt. The 300 is also often the first brevet with lights on and a night section, so fatigue and cold arrive together.

The plan keeps the long ride as the key session and adds durability rides in the Build phase: 2 to 3 hours of Zone 2 followed by sweet spot or tempo blocks, so you learn to produce steady power on tired legs.

Sample 16-week 300 km brevet training plan

Generated by MeepMeep's plan builder for a rider training about 5 hours a week now, with a ceiling of 8 hours, five riding days and the long ride on Saturday. Race pace is set at about 70% of FTP. Your own plan starts this week and ends on your event date.

The phases

  • Foundation · 3 wk

    Easy volume and a gentle introduction to each kind of session.

  • Base · 4 wk

    Aerobic volume, tempo and low-cadence strength. The long ride grows steadily.

  • Build · 4 wk

    Sweet spot and threshold to raise FTP, plus durability long rides with efforts after a long pre-load.

  • Specialty · 3 wk

    Event rehearsal: race-pace long rides with full fueling, back-to-back days and a durability test.

  • Taper · 1 wk

    Volume drops by roughly half while intensity stays, so you arrive fresh.

  • Event · 1 wk

    Openers, carb-loading and the event itself.

300 km brevet training tips

  • Rehearse the night: ride your Specialty long rides in the evening with your lights and layers.
  • Plan your food per stage, not per day. Know what you will eat between each pair of controls.
  • Expect your pace to fall in the second half. Riders who hold power late are the ones who finished the first half easy.

Key workouts

300 km brevet training questions

How many hours a week should I train for a 300 km brevet?

In this sample, weekly training starts around 5.0 h and peaks at 7.6 h in week 14, with an easier week after every three. Riders with more time can set a higher ceiling in the app; the plan never schedules more than the most hours you enter.

How long should my longest training ride be for a 300 km brevet?

The plan's longest indoor ride here is 3 h 3 min. Indoors, 5 to 6 hours is plenty: the work is steadier than outdoors and back-to-back days add the extra fatigue. Long outdoor rides and qualifying brevets can replace any long ride in the plan.

Can I train for a 300 km brevet indoors?

Yes, for most of the work. Indoor sessions are ideal for durability blocks, steady Zone 2 and tests, and they fit around work and family. Do some long rides outdoors with your event setup to practise navigation, night riding, stops and comfort.
