UK's Hardest Hundred: Kent & Surrey Hills

Cranleigh, Surrey

Cranleigh, Surrey

Sun 12th September 2021

Starting at 07:45

Organiser's Description

Ride one of the toughest routes in the South East and take on 13 major climbs (including 8 in the Top 100 climbs) in Surrey & Kent.

From Cranleigh, the Surrey Hills bring the steep climbs of Barhatch and Coombe Lane, before heading along the North Downs ridge to Kent. The toughest part of the route is the 50km between Sevenoaks and Redhill, with some super punchy climbs including Toys Hill & Chalkpit Lane before coming back into Surrey for a sharp last 20km over Leith Hill.

With over 3,000m of elevation, this is as tough a ride as you can get in the South East and a real challenge to put in the calendar for 2021.
