Marathon Events in London 2025-2026
The marathon distance is 26.2 miles, or 42.2km. They are often seen as one of the main goals in a runner's lifetime. Completing one is a real feat of mental and physical resilience, and requires a serious amount of commitment and training if you are seeking a bragworthy time. The London Marathon is one of the most famous and biggest marathons in the world, and is one of the six world marathon majors. Each year it attracts over 40,000 participants and 800,000 spectators. It is also a relatively flat and fast course, so it is a great opportunity for anyone seeking a new PB. The London Marathon is also famous for its fundraising ability - it has raised over £1 billion for different charities since it started in 1981. There are other marathons in London available, which don't have as large crowds but access some stunning scenery, such as long the Thames path.
