Race times and what to wear

Today’s the day the London Marathon 2022 gets underway, with Sir Mo Farah now set to miss out on the men’s race with a hip injury.

50,000 runners are expected to start the course in Greenwich Park, a new record for the largest marathon ever staged, while a further 50,000 are ready to join in the fun with the virtual course which can be completed any time between 00:00am and 23.59 on Sunday 2 October on a 26.2 mile course of the runner’s choice.

After two years of uncertainty around the event, 2022 will be the biggest ever London Marathon and will also mark the final time the event is held in October.

Due to the Covid-19 pandemic, the race was pushed back to the autumn season, but 2023 will see it return to April once more.

This year will also mark the first year the London Marathon is partnered with TCS - one of the world’s biggest IT companies and sponsor of the marathons in New York, Toronto and Amsterdam.

Speaking about the partnership, The TCS head of sports sponsorships Michell Taylor said: “We really see running as another engagement opportunity, similar to golf in some ways. We’re not there yet but in our minds this is where we’d like to see things go.

What to wear for London marathon this weekend

Many participants wear old clothes or a bin liner to keep themselves warm while they wait at the starting line up. September and October are still usually months where shorts and T-shirts are worn, but while waiting for the race to begin, old clothes are vital in order to keep participants warm.

In mild weather, the TCS London Marathon website recommends wearing lightweight cover-up pieces, such as a long-sleeved T-shirt.

For those wearing shorts and t-shirts, wicking fabrics are suggested that can draw the sweat away whilst also featuring extra ventilation at key body zones (these will differ between men and women).
