With a 3/4 option, Half & Quarter Challenges, the Cirencester 10K – there’s a great weekend in the Cotswolds to look forward to!

A perfect choice if you’ve done a Half Challenge before – and want to ‘up’ the distance without committing to a ‘Full’ option. The route is 3/4 of the Full Challenge – so starts at Painswick, takes in the fantastic 2nd 1/4 Challenge route to Wotton, and then on through the Cotswolds to the finish line at Cirencester basecamp (the 2nd 1/2 of the Full Challenge) after a tough 76 km. Do it as a ‘Continuous’ challenge – OR rest overnight after the 1st 33 km & camp at our Wotton basecamp (or hotel/ B&B) – and do the remaining 47 km (2nd half) on Sunday morning.
