42 KM RBB or RB

42,9 km
12h00 RBB / 12h05 RB

Revolution for the "run bike bike", the distance goes from 80km to 42km in 2018 but there will be two possible formulas and two classifications: a formula with 3 participants including 2 mountain bikers and a formula for two participants for a more classic "run & bike" . It will be a matter of starting in teams of two or three riders who will be able to take turns on the bike (s). The participants will have to stay together. To make sure, the rider will have to wear a 'relay batton'.

Advice to teams of 42 RBB
Based on the experience of the first editions, here are some tips:

  • Avoid placing the slowest rider on the bike on the hills. This biking part would not allow him to recover, as is often the case for cyclists who can stay up with the runners.
  • It is not easy to keep relays from 30 to 40 seconds (used on classic "run and bike" short) over a distance of 42km.
  • The length of the relays varies according to the individual, the strenght of the team and the progress of the event but generally and at least at the beginning, the runner runs at least 3 to 4 min.
  • Reminder, except mechanical problems of a bike (which would be delayed or who would have abandoned), the 3 teammates must remain "together" and there can be only one rider at the same time by team. Translation: a cyclist on the team can not leave his bike and start running until the rider is at his height and did not relay the relay (an armband, given with bibs).
