On One Hundred Mountain Marathon- Sunday 24th July:

This is an epic and awe-inspiring challenge for both rider and machine. Riders of all abilities need look no further for the ultimate challenge. A single loop will explore the very best of Dalby Forest, home of the UCI World Cup, taking in some of the world class fast flowing singletrack and forest roads before heading out on to the Moors.
On One Hundred Mountain Marathon

Riding over ancient byways and classic natural singletrack the route takes in some breathtaking scenery before heading back down some awesome descents. Almost exclusively off road, the aim is for everyone to finish, and though there is a competitive element there won’t be strict time restrictions and you won’t be swept up unless you want to be. If 100km is a little too far for you we’ve got a the Half (50km) or Mini (30km) Marathon distance to cut your teeth on- great if you want to ride with a group or the family.

Great Attractions!

Purple Mountain will also be running  a series of Skills Sessions though out the weekend, great for the kids and those who want to polish up on their singletrack sections. There’ll be something for everyone, so why not make a weekend of it, come along and get involved! The start and event arena will be based in the heart of Dalby Forest with full facilities, on-site camping and toilets. Demo bikes, trade stands with all the latest kit, tech support and catering with all day BBQ, will all be on hand to make the weekend ‘On-One’ to remember.

Safe, Fun and Challenging!

All courses will be supplied with regular service stations where food, water, technical support, marshalls and medical cover will be available. If for any reason you have a problem or want to reduce the distance but still want to complete the challenge, there will be shortcut escape routes that bring you back to Dalby under your own steam. The events are non-competitive, but you will get an individual finish time and instead of prizes for the winners we’ve got some fantastic spot prizes provided by our sponsors, On-One, Planet X, Scott, Osprey, Fisher Outdoors, Zyro and Mule Bar. For those riding On One and Planet X bikes there will be a whole series of extra special spot prizes. In addition every rider will receive a fantastic goodie bag packed full of goodies.

Free Camping!    

Based in the heart of Dalby Forest at Adderstone Field FREE Camping will be available from Friday night through to Monday morning. Riders will benefit from all usual facilities, water, toilets and onsite catering. A quiet area will be set aside for those wanting a good nights kip before their Marathon Challenge, and there’ll also be a family friendly area for those with kids.

    I rode the "100km" route posted on the net yesterday. Its about 75km with more than a smidge of tarmac. Nice route though with a couple of stingers in the tail. Singletrack down from Lilla Cross is going to be interesting...

    Hi Pete, we've asked for the route from the organisers of the event, Purple Mountain. We'll stick it up for you guys to take a look at when we have it.

    Any chance of the mtb route being shared on the site (post event?) as I don't know whether I'll be able to attend but it sounds like a great route. Cheers.
