Buff Enigma Quadzilla

Buff Enigma Quadzilla is a four-day challenge in Milton Keynes from 4 to 7 February 2027: four marathons in four days, alternating between the standard route and a reverse route, with a 09:30 start each day. It was created by David 'Foxy' Bayley, who has completed more than 100 marathons and several 10-in-10s, and the event is known for its friendly atmosphere, reliable organisation and collectable themed medals.

The races are usually held on quiet lakeside paths, which makes for a controlled, repetitive effort where pacing and recovery matter as much as speed. Complete all four days to earn the coveted Survivor hoodie and a lifetime Green Number, a small, exclusive club celebrated by the community. Born from a charity run in 2010, the Quadzilla has become Enigma's flagship event and a winter fixture for marathon enthusiasts.
