There is still time to register for the Chiltern 100 bike challenge on 26th June 2011. The event gets its name because of its choice of two distance events; 100km or the even-more gruelling 100 miles – both take riders through countryside often seen in Midsomer Murders.

Whichever distance you plump for, charity is guaranteed to be the winner as organisers Action Medical Research require that race entrants commit to raising a minimum of £30 sponsorship.

There are expected to be 600 riders at the Henley Rugby Club starting line and after they set off they will speed past some of the finest countryside in the county of South Oxfordshire.

After a steep climb into the beautiful Chiltern Hills, the cyclists will pedal through Turville, where the Vicar of Dibley was filmed.

The £28 registration fee covers lunch and refreshments, all of which will be provided in the bustling market town of Wallingford (‘Causton’ in Midsomer Murders).

Having been fed and watered the cyclists will speed around the Thames and return to picturesque Henley where post-event massages and ride mementoes will be available.

This will be the third year that the race has been run and the worthiness of the charity which organises the event has great appeal for the competitors.

Action Medical Research has been instrumental in medical breakthroughs such as the UK polio vaccine and pregnancy ultrasound scanning.

Your pedal power could increase its research power so hurry up to register!
