Overview

Logo UTMB 2021 ENThe Uccle-Boitsfort racecourse is the scene of the start and finish of the 42km (600 D +). The course, credited with 2 new qualifying points for the UTMB®, starts directly in the Sonian Forest and goes towards the castle of La Hulpe (mid-course) before returning over single tracks crossing several nature reserves. This itinerary summarizes two strong features of Brussels and its region: its European destiny and its many green spaces.

Note: The stated elevation gain on this website is calculated by ITRA (this number can vary depending on the website and according to the calculation method).

Overview

It will be a matter of starting in teams of two riders who will be able to take turns on the bike. The participants will have to stay together. To make sure, the rider will have to wear a ‘relay batton’.

Advice to teams of 42 RB
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 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).
