In the middle of January, with 17 hours of darkness, over 850 competitors will head north of Inverness for one of the world's toughest mountain bike races - the Strathpuffer24. Now in it's eleventh year, the 2016 event promises to be the largest ever 'Puffer. Conditions are extremely testing, with ice, snow and mud pushing the competitors and their bikes to the very limits. Entries sold out in minutes for this now iconic mountain-bike event which attracts riders from all over the UK and beyond. It's not one for the faint-hearted. See www.strathpuffer.co.uk.
