Take part in a challenge event and raise money for Thames Reach

Thames Reach has places in a number of prestigious events throughout the year. From the Brit 10k, Royal Parks Half Marathon and London Triathlon, we have an event that will suit most abilities.

If your interests are more towards having fun rather than setting a new personal best, why not try the London Duathlon, a run, cycle, run triathlon with a range of distances to suit all abilities, designed for friends and family rather than athletes.

For the cyclist, you can take on the famous London to Brighton Bike Ride, 54 miles through beautiful countryside, with stunning views from Ditchling Beacon, before finishing in style along Brighton sea front.

You will receive a Thames Reach running or cycling t-shirt, a training plan, and help with publicising your challenge.
