Organiser's Description

So here’s the challenge, cycle 360 km around London on bridle and byways in 24 hours.

Don’t underestimate LOGC, it’s one of the toughest rides I know, out of over 40 starters last year only one person completed the challenge - me!

There are 4400 metres of climbing spread over 30 climbs, the routing app reckons you’ll burn over 10,000 kcals - all of this and you’re never more than 25 miles from the centre of London.

Starting at stupid o’clock in the morning at Greenwich, ride out along the Thames before climbing the North Downs and then on to the unexpectedly lumpy Greensand Ridge, by lunch you should be beyond Reigate...

Drop down into Guildford, across the Surrey heathlands, heading for tea in Maidenhead, dinner in the Chilterns before riding across the top of London overnight, Experience dawn breaking through Epping Forest, and if you get back to Greenwich within the 24 hours, you’re a frigging awesome!

If this all sounds like far too much, you can enter the 100, 140 or 180 km day enduros and enjoy some of the best gravel riding in the Southeast.

All efforts are timed and the results will be posted live on the Hidden Tracks website.
