Hybrid races near London

London's indoor races use the big exhibition halls. At ExCeL on Royal Victoria Dock, Custom House (Elizabeth line and DLR) is nearest the west entrance and Prince Regent (DLR) the east; they're about a kilometre apart through the building, so check which end your race uses. Olympia is next to Kensington (Olympia) station on the Overground's Mildmay line, and District line trains run there from Earl's Court at weekends. Further out, Farnborough International in Hampshire is 1.5 miles from Farnborough Main, about 35 minutes by train from Waterloo. Magazine London, an events space on the Thames at the tip of the Greenwich Peninsula, is a three-minute walk from North Greenwich on the Jubilee line.

Track racing happens at Lee Valley Athletics Centre in Edmonton, which has indoor and outdoor tracks and is a short walk from Ponders End station, and at the Sir Mo Farah Athletics Track at St Mary's University in Twickenham, five minutes' walk from Strawberry Hill. The calendar splits by roof: hall races tend to fall in the colder half of the year and outdoor track racing runs from late spring into autumn, while Lee Valley's indoor track keeps shorter races going through the winter.

Several series race here alongside HYROX. Deadly Dozen is twelve 400 m track runs, each followed by an exercise station it calls a Labour, for solo athletes, pairs or relay teams of four. Its Deadly Sprint is half a Deadly Dozen indoors, with 200 m runs and half the reps, and its Hybrid weekend pairs the Sprint with the full race outdoors. MacTuffX races only on outdoor tracks, with ten functional fitness exercises on the infield and 400 m laps between them (800 m on its 2X option). METRIX is a fitness competition for pairs across five stations, and Turf Games began in London in 2018 to unite the city's fitness community.
