The Thames Ring 250, the UK's longest non-stop running race

Via: Alastair Humphreys – The UK’s longest ever non-stop running race, the Thames Ring 250

The UK’s longest ever non-stop running race is the Thames Ring 250. 250 miles, to be completed within 100 hours. Nearly ten marathons in four-and-a-bit days…
In wonderfully understated British style, the Thames Ring doesn’t even have a website. You can see the route map here and some photos here from this magnificently understated, yet heroic challenge.
I went along to the start of the race in the unlikely surroundings of Streatley Village Hall in Berkshire. Here’s a 90-second video of what I found.
