Ten half marathons you can enter in London in autumn 2023

For those stepping up their distances in training for the 2024 London Marathon or looking for a good time over 13.1 miles, the autumn is a good time for a half marathon.

As well as the cooler, but pleasant, weather, the falling leaves can also provide a beautiful scene - if you are able to notice these things while pounding the pavement.

There are many places around the capital to test yourself over a half marathon, whether you are looking for a new PB, a different kind of challenge, or stepping up to the distance for the first time. The 2024 London Marathon will be on April 21, so for anyone new to running who is attempting the full distance, an autumn half will be a useful stepping stone.

Here are ten of the best half marathons in London this autumn and if there is just about time to train if you are ready to go.

Victoria Park Half Marathon - Saturday, October 14

For those in the East Side, Victoria Park does offer a flat course that is perfect for a PB - although it is several laps of the same loop. That said, it is known for having a good, ready crowd of spectators and is in sight of the Olympic Park should you need more inspiration.
