If you are a cyclist and looking for an unforgettable challenge on the UK’s greatest two day cycle event, you’ve come to the right place!
Our 155 mile loop, which starts in London and quickly heads out to the beautiful surrounding countryside, offers a variety of options to challenge all levels of fitness and expertise.
Those who love multi-day rides and would prefer to split the distance across two action-packed days – 82 miles and then 73 miles – will find the Weekender is the perfect option. This also includes the perks of our midway Festival Basecamp which offers camping facilities, hot showers, bars, food and live music.
If you’re looking for something extra challenging and wish to attempt all 155 miles in on go, then our ULTRA is for you. This option, not to be taken lightly, is the same as cycling from Tower Bridge to Cardiff Bay! Just think of the sense of achievement when you complete the full loop of London and surrounding countryside. Hero status awaits at the finish line!
We know that taking on your first multi-day ride can be daunting, but we are here to help you unlock your potential. Click below to read what some of our past participants said about our event.
We strive to offer unrivalled support, from training plans to roadside mechanical assistance and Basecamp massages. Casual weekend rider or Tour de France hopeful, we are here to help get you across the finish line!
We believe cycling is for everyone, and we’d love you to bring your family along to help celebrate and inspire the next generation of cyclists.
Our Windsor Basecamp has something for all ages, from bouncy castles to live music and even a London Bus Bar!
There are lots of reasons why our riders come back year after year and give our event 5-star reviews. Check out some testimonies of previous riders who joined us to conquer the London loop.
"I don't know where to begin! This weekend event was so incredibly well organised with wonderful friendly staff who created such a great atmosphere... The route signs were everywhere that you couldn't possibly get lost on such an epic route full of beastie climbs and well-catered pit stops."

"What I really appreciate with Threshold is that if something doesn’t go as well as it might (which, of course, happens on events of this scale) they put it right next time. I’m a huge fan of these events and can’t recommend them highly enough. Great route, logistics, support and attention to detail. See you next year!"

"Absolutely amazing weekend! This is the first organised ride I have been part off and I struggle to think of how it could have been any better!! Everything about the weekend was superb, the route was well organised and signposted, the pit stops were well stocked and the support given to all of the riders as they reached the stops was amazing!"
