Descente London Duathlon (Sunday 16 September 2018) is a run-bike-run event offering athletes of all abilities the chance to race through the stunning surroundings of Richmond Park while on completely closed roads. Alternatively, you can take on Descente RUN10, London's most beautiful 10k run (we think!). All entrants receive a fantastic Descente cycling jersey or technical T-shirt.

  • Did the Ultra Duathlon in 2018

    Absolutely loved it. If you want an event to really push yourself an Ultra Duathlon is the one.It is a little repetitive doing laps of Richmond Park but actually knowing where you are, what you have coming up and how long to go is helpful.The last 10k is the hardest thing i've done so the sense of accomplishment was awesome!!!Event is set up well, transition areas are good.So local to London means easy for friends and family to come and watch
