Billed as the UK's largest mass participation winter event and the largest 10km run in the capital, the London Winter Run is gearing up for its fourth outing on Sunday 4th February.
Many of the London Winter Run's more than 20,000 participants are expected to raise in excess of £2 million for an array of charities, including Cancer Research UK, which is helping to organise the race.
So how about heading along to the course to support the determined runners as they push themselves from the starting line in Trafalgar Square all the way to the finish in Whitehall, close to Downing Street.
Other famous landmarks along the way where you can cheer on participants include St. Paul's Cathedral, Somerset House, and Horse Guards Parade.
In the 2017 London Winter Run, the fastest runner completed the course in just under 34 minutes, while those taking it at a more leisurely pace came in a couple of hours later. But for most of those taking part, it's not about getting to the finish in record time, but instead having a fun day out and raising cash for good causes.
For 20 percent of the London Winter Run's participants this will be their first-ever running event, so having supporters like you lining the route will hopefully give them the boost they need if their energy levels begin to dip.
The first group of participants will set off at 9.30 am, so wrap up and head down to Trafalgar Square on 4th February to help get them off to the best possible start!
