Our sportive is named in honour of the legendary home of the codebreakers; Bletchley Park – the National Codes and Cipher Centre
You have a choice of two distances:

• Enigma Sportive of 100km with around 2,800 feet of climbing
• Colossus Sportive of 100 miles with around 4,500 feet of climbing

Both distances feature an outstanding circular route through the country lanes surrounding Milton Keynes and Bletchley taking in the two counties of Buckinghamshire and Bedfordshire. The 100 mile route will have two feed stations, you will visit the one at Salford twice. The 100km route will visit the Salford feed once. The route is rolling with a few nasty little climbs, especially near the Brickhills, where both routes pass.
