Codebreaker Sportive


Organiser's Description

Named in honour of the legendary home of the codebreakers - Bletchley Park – this event offers a choice of two distances: the Enigma Sportive, 100k with around 2,800 feet of climbing; the Colossus Sportive, 100 miles with around 4,500 feet of climbing. Both routes feature an outstanding, circular, rolling route through the country lanes surrounding Milton Keynes and Bletchley, and a few nasty little climbs!
