Participants start the 2012 Oggie 8

A mountain rescue team is looking for adventurous walkers and runners to tackle a fundraising challenge.

The Oggie 8 Challenge is a testing circuit of eight 3,000ft mountains around the Ogwen Valley in Snowdonia.

Proceeds from the August event will go to the Ogwen Valley Mountain Rescue Organisation, one of the busiest in the country with more than 100 callouts each year.

The team, whose patch includes Tryfan, the Glyderau and Carneddau, needs £60,000 annually to operate.

The Oggie 8 starts and ends at the team’s Bryn Poeth headquarters and takes in Carnedd Llewelyn, Yr Elen, Carnedd Dafydd, Pen yr Ole Wen, Y Garn, Glyder Fawr, Glyder Fach and Tryfan.

There are no compulsory scrambles in the route as it avoids Bristly Ridge and Tryfan’s North Ridge.

A spokesperson for the event said: “The Oggie 8 Challenge takes teams a range of times to complete the circuit depending on fitness, weather and navigation.

“Some may take up to 12 hours to complete the course, while faster teams may halve that. Although organisers are keen to stress that this is not a race and that it’s the taking part that counts.

“The course is fully marshalled and organised as a major event with an excellent after party at Bryn Poeth.”

The event takes place on Saturday, 3 August, with participants taking part in a mass start.

Teams can consist of between four and six members, and each entrant is asked to raise at least £25 in sponsorship for the Ogwen Valley Mountain Rescue Organisation.

The minimum age for entrants is 18 and organisers now accept online entries as well as postal applications.

The route is available on grough route for subscribers. Type ‘Oggie’ into the Route section of the Search menu.
