Great challenges need spectacular settings! Explore the Isle of Wight’s stunning southern cliffs, pass the iconic Needles and head to historic Cowes. Full Island Challengers continue to Ventnor before returning to our Chale Basecamp after an epic 107km journey.
With full support throughout and a choice of Full, Half and Quarter Island Challenges, plus the Southern 50km Loop and 10-mile Medina Estuary routes, there’s a challenge for everyone!
Ferries from Southampton and Portsmouth make getting to the island easy, with a range of transfers available for foot passengers.
UK’s #1 series of treks & trail runs for a wide range of ages, fitness & experience levels. Choose your Challenge – do it at your pace, and there’re 24 events to choose from. Our support enables you to go further, whilst enjoying the great outdoors, camaraderie, and the challenge!
Marquee rest stops, lots of food & drink, medical & massage teams, with a fully signed route & GPS tracking to guide you. A big finish-line celebration awaits with an amazing sense of achievement, and once the aches subside you’ll feel energised, up for more of life’s challenges – and, maybe, personal horizons redefined!
Good preparation is key, and you’ll have access to our Challenge App – with training guides, maps, online forums, and the latest news & updates.
Rest Stops every ~12.5 km with ‘major’ ones every ~25 km. Marquee cover, large medical & welfare tents, catering services, seating areas for recovery, changing rooms, lots of toilets, and a friendly welcome!
Pink arrows + glow-sticks (at night) mark the route, and with Google route maps in the App you won’t get lost on an Ultra Challenge®!
Our Timing System scans you at rest stops, with your progress logged and monitored by our Control Room.
+ an APP for your mobile with GPS Tracking – which you can share in ‘real time’ with family & friends – without draining your phone’s battery – and you also get all the info on the route lying ahead!
We pride ourselves on the quantity & quality of our catering, and whichever distance you are on – meals, snacks & drinks are included.
Campsites at our main start / finish Chale basecamp for weekend camping – and one at Cowes halfway point for rest & sleep if you’re on the 2 day ‘Daylight’ 106km option, or if you finish / start a `53 km ‘half’ Challenge.
Book an inclusive package or ‘pitch your own’ – there’re showers and chill out areas. Check out the ‘Bookable Extras’ for details.
Doctors, Paramedics, First Aiders, and Massage Teams at Rest Stops + ‘Self Help’ areas with blister plasters, talc, Vaseline, and tape if you want to patch your own feet.
Mobile Emergency Medical Teams are only a phone call away, via our 24 hour Control Room.
Our Cheer Squad ensures you get a memorable finish. You’ll get a medal, finisher’s T-shirt, and a glass of fizz, before heading to for a meal and a well earned rest.
Download your official Challenge Certificate when you’re ready.
Optional shuttle services from Cowes Ferry Port to our basecamps in Chale (main start) and Cowes (for some start options) – and back at the end of your challenge.
Plenty of parking if you’re driving – and for supporters to meet you. Check out the ‘Bookable Extras’ for details.
Looking for a great event for your team? These events are the PERFECT solution.
Your Team will be energised, exercised, bonding & motivated on a fun, accessible, safe, high quality outdoors event – maybe supporting your ‘charity of the year’.
