You can expect some challenging terrain on our Chiltern Challenge 100 bike ride as you pedal to help save and change children’s lives. With a choice of three distances, this bike ride explores quaint villages as the route meanders through the lanes of Oxfordshire, Buckinghamshire and Berkshire. Henley and Pangbourne on the banks of the Thames feature along the way as does the village of Brill with its landmark windmill.

The Chiltern Challenge offers a Cool 42 mile route that is ideal if you’re new to cycling or looking for an early finish! Our Classic 71 mile route is more challenging as is the Champion at 103 miles which is ideal if you’re an experienced Sportive rider.

Expect a great day in the saddle with the Action Medical Research team on this cycling event with first class support throughout the day.

Action DIVA Chiltern  - The Chiltern Challenge 100 includes our special promotion to get more women cycling. If you are new to cycling try the 42 mile route. Tick the I’m a DIVA box when you enter.

Jack's story

Obstructive sleep apnoea

Jack was born with Down syndrome. His parents noticed problems with his breathing when he was nine weeks old. It took another two years for him to be diagnosed and treated for obstructive sleep apnoea (OSA).
