Half Marathon races near London

London Training Notes

London hosts 204 Half Marathon races in 2026 within 80 km of the city centre — upcoming dates, recurring series, and other races nearby, all in one place.

Locals run London by linking parks, canals, and the river. Hyde Park is a dream park for run lovers, and Kensington Gardens keeps the easy miles neat. Regent's Canal gives you proper base miles from Angel toward Victoria Park, Limehouse, Wapping, and Tower Bridge. Victoria Park has a 4 km outer paved lap when intervals need less fuss. Run clubs cover every corner, from London City Runners and East End Road Runners to Serpentine Running & Triathlon Club, Track Mafia, and On Run Club. The Thames Path runs 2 miles from Greenwich to The Mall. The Big Half, Royal Parks Half, and London Winter Run 10K keep the calendar honest.

Locals ride laps before work, then point the bike out of town when the legs ask for more. Regent's Park gives weekday training laps, and Richmond Park gives about 10 km per loop with small hills and a woodland section. Cycle Club London rolls from North London into Hertfordshire, Essex, and beyond, with gravel rides most weeks. London Dynamo brings road racing, time trials, track, gravel, cyclocross, and sportives. Islington Cycling Club and North London Dirt keep the route book lively. The Bun Run, London to Brighton, London Essex loop, Kent loop, and St Albans loop feel like anchor rides. The climbs sit in Surrey Hills, Box Hill, Biggin Hill, Ally Pally, and the North London Heights. Lee Valley Velo Park gives crit legs a clean circuit.

Spring, Summer, and Autumn are the best blocks for London training. Summer brings warm days, and London's average July high reaches 23.5°C. Locals use the long light for Z2 on the Thames Path, Regent's Canal, River Lea, and Limehouse Cut canal. Richmond Park, Bushy Park, Hampstead Heath, and Wimbledon Common feel bigger once the evenings open up. Winter keeps the city rideable and runnable, with cool weather and little temperature variation. Heavy snow is rare, but snow usually falls at least once each winter. Cyclists add clip-on mudguards because London is more wet than icy. Runners keep long runs early on Sunday when the paths feel lighter.
