It's a sponsored charity challenge held every July, consisting of a 17-mile hill section over the historic Corrieyairack mountain pass (2350ft) followed by a 26-mile road section. Runners, bikers, duathletes and joggers/walkers of all levels take part so consequently there is great camaraderie and mix between 'elites' and 'have a go's'.

From humble beginnings in 1993, the event has gone from 110 entrants to 500 reached in 2005 and 2006, £80k raised in 2005 and £75k raised and received in 2006. Now in its 15th year, the Corrieyairack is well established in many people's annual running and biking events calendar.

The ethos of the event - 'A Challenge for All' - means that everyone is welcome to take part regardless of ability, age or experience. The charity behind the event - Badaguish Centre - a small registered Scottish Charity has the same ethos and provides outdoor activity holidays and respite care for people with special needs from all over Scotland and the UK.

The 'Corrie' as it is now fondly known, is the biggest fundraising event of the year for the Badaguish Centre, based near Aviemore. Open to teams of 3 competitors who raise money through sponsorship, each competitor has to run, jog, walk or bike the hill section and then complete the road cycle section.

The race starts at Fort Augustus close to the well-known abbey and after 2 tarmac miles to warm up, turns off and begins to climb the winding hill track of the Corrieyairack Pass - Scotland's highest mountain road once used by Bonnie Prince Charlie. The long haul to the summit is eased by strategically placed water stations before the competitors finally sight and then reach the summit check point, appropriately manned by the Cairngorm Mountain Rescue Team. The descent starts with the infamous 'zig zags' which get the competitors down from the summit wind and rain (hardly ever!) and sets them on the way along the steadily descending rocky track to the Melgarve Bothy water station. From here the remaining few miles to the Changeover Point are on an 'undulating' tarmac estate road.

The remote and usually quiet location of Garva Bridge is the event changeover point but race day sees it transformed into a Formala 1 pit lane! Staffed by a team of volunteer helpers, runners are received, fed, watered, changed into cycle kit, paired up with their trusty bike or wheel/tyre change, given copious encouragement and dispatched out again - all usually within 30 seconds!
