We're big supporters of the MTB-Marathon series for some very simple reasons, but chief among these is that they're an excellent way to spend a weekend. They're great fun, offer a laid-back atmosphere and get a little crazy when 1,000 riders try to squeeze through a Welsh village that wasn't necessarily designed with MTB enduros in mind.

The MTB-Marathon crew have just released a limited edition jersey, of which just 100 have been printed. They've been produced by Canadian clothing experts Sugoi and are selling fast, but we managed to grab three before they all disappeared. We've also got 10 runner up prizes in the form of a MTB-Marathon thermo mug, perfect for your favourite post-ride recovery drink.

All you have to do to stand a chance of getting your name pulled out of the hat is to follow the link below and enter a round of the MTB-Marathon, online. It can be any of the remaining rounds - Builth Wells (3 July), Selkirk (31 July) or Ruthin (18 September).

To make sure you're in the running, you'll need to add "Bikemagic" to the third address line, so that we can identify you and add your name to the digital hat.

And if you need reminding of the two rounds which have already taken place, here's the Rhayader and Builth spring opener.
