Did you just turn 30? Are you having a quarter-life crisis? You’ve probably thought about running a marathon (or half). We’re only teasing, but the long running races are showing no sign of letting up their grip on the collective consciousness of millennials in London any time soon.
Coming up soon is the Big Half 2025, a half marathon that’s taking place in London this weekend. But after training for weeks, you probably don’t want to mess everything up by turning up at the wrong time, or to the wrong place. So, nipple tape and talcum powder at the ready, here’s all the information you need if you’re running the Big Half 2025.
Date
The Big Half 2025 takes place on Sunday, September 7.
Start times
The official start time of the race is 8.30am. In previous years starts were staggered every 10 minutes after.
Participants will have four hours to complete the race. If they haven’t finished by then they can continue, but must run on the pavement. The Big Half team will stay to support runners until they cross the finish line.
Route
The 13.1-mile race kicks off next to Tower Bridge – make sure to check which assembly area you are due to be at, as there are two: north and south. Runners will then run east to do a loop around Canary Wharf, turn back on themselves and pass through Wapping before crossing Tower Bridge in Bermondsey. Runners then pass through Rotherhithe, Surrey Quays and Deptford before crossing the finish line at the Cutty Sark in Greenwich.
