Leaving Wallingford via Crowmarsh, the first climb up Clack’s Lane is a gentle affair but guaranteed to get you nicely warmed up for the challenges to come. The first of these is Swyncombe Hill, with gradients maxing out at 12%.
You’re in the heart of the Chilterns now, and despite being early in the ride, you’ll need a rest after Swyncombe Hill. You’re in luck, as the fast descent from Cookley Green to Pishill is a chance to catch your breath and rest your legs ahead of the next climb up Balham’s Lane. The route then meanders up through North End to Christmas Common, and on to the Feed Station at Cowleaze Woods where you can grab a snack and top up your bottle.
Feeling refreshed, it’s time to head on to the top of Aston Hill. Here is where the 60km route heads for home, with the longer routes turning right towards Stokenchurch and heading out towards Princes Risborough. Watch out for the tricky descent out of Radnage, then brace yourself for a very tough climb up Smalldean Lane where you’ll be grinding up gradients of more than 20%. Thankfully it’s only a short one!

Heading for home now, you’ll pass through Great Milton and past Raymond Blanc’s Le Manoir aux
