Find races in London this weekend and beyond. Compare major UK marathons, ballot events, and city road races with dates, distances, and registration links.
The London Marathon is one of the world's premier races, and London's wider calendar keeps the page relevant well beyond a single ballot-driven weekend.
Best season: Spring and autumn are the strongest periods, especially around the marathon and larger half marathon weekends.
Best for: bucket-list marathons, major half marathons, runners balancing prestige and logistics
London is a core guide page because runners need help with a real decision, not filler text. The city offers unmatched marathon prestige in the UK, but that prestige comes with entry pressure, cost, and planning tradeoffs.
Look at entry access, accommodation cost, and race-day logistics as seriously as the event itself. London is an extraordinary target, but it is not automatically the best practical race weekend for every runner.
Start with marathons and half marathons above the grid. If London feels too competitive or expensive for the same training block, widen to the rest of the UK and compare other big-city options directly.
