Cool Runnings 40th Anniversary Marathons & Half Marathons

This event offers marathon and half marathon distances on lakefront paths around Caldecotte Lake in Milton Keynes. The course uses compacted gravel with some concrete sections and short stretches of mud and grass. The route is traffic-free and starts and finishes at the Caldecotte Lake Pub.

Races are held as laps around the lake: marathon entrants complete 7.5 laps and half marathon entrants complete 3.5 laps. The course elevation is described as flat. Entry options include races on both Saturday and Sunday and entrants may choose to enter one or both race days.

Practical details provided for entrants include a bespoke finisher's medal, water stations, toilets, a timekeeper, and parking. All entrants must be 18 or older. Cut-off times are 7 hours for the marathon and 3.5 hours for the half marathon; entrants who exceed these limits will be recorded as DNF.

Race numbers are collected from Race HQ at the Caldecotte Arms; organisers advise allowing at least 20 minutes for this process. There is no secure baggage drop, but the looped course means bags can be left near the start and finish where people will be present. A large car park is available at the pub. The closest train station is Bow Brickhill, which is served by the Bedford line and is near a local bus connection to the event site.
