Reading Ultramarathon Events

The Dixons Carphone Race to the Stones is a fully supported 100km challenge along the iconic Ridgeway. You can run it or walk it from the start line in Oxfordshire to the finish next to the 5,000-year-old stone circle at Avebury. Complete the 100km non-stop or break it into two days staying at our overnight basecamp.

The WW50 is a 50-mile foot race consisting of 5 x 10-mile loops on forest trails, entirely within Wendover woods. The course mixes some of the most enjoyable trail running to be found anywhere, with wide, soft trails including smooth descents and runnable climbs. These sections are contrasted with some much steeper ascents and descents scattered throughout the loop. Runners will work hard for a finish at this race which will also act as the fourth and final event in the 2018 50 mile slam.

The Thames Ring 250 is a 250mile trail race starting in Streatley-on-Thames and following the route on the map in an anti-clockwise direction. The route is mainly on canal and riverside paths and relatively flat.

Runners have 100 hours (4 days 4 hours) to complete the run, navigating using maps and being supported by checkpoints every 25 miles or so.

Its an extremely tough run testing runners endurance to the limit along with long hours with little sleep and long dark nights.

Who will it be this year??

The clue is in the name - You really, really won't want to miss out on this one.

Fancy dress is definitely the order of the day. Who will you come as?

From 5km to ultra, you can complete as many, or as few laps as you like of a 3.28 mile, out and back, course along the beautiful river Thames. We welcome all abilities of runner - complete one lap and you're both a finisher and a winner in our eyes, or keep going and see how far you can get in the full 6-hour time limit and everyone gets the fabulous bespoke finishers' medal.

This ultramarathon is the last leg of The Monster Triathlon and takes you along the banks of the Thames. The route utilises much of the Thames Path as it winds its way towards the finish venue in Richmond.
