Applications are now open for adventurers to take on eight mountainous peaks around Snowdonia.

The tough route will see determined thrill-seekers take on each 3,000ft tall summit around the Ogwen Valley over the course of a day in a massive test of endurance.

Avid ramblers and seasoned runners are encouraged to apply for the challenge - which takes place in August - in a 15 mile circuit that could take up to 12 hours to complete.

The route, known as the Oggie 8, is an imposing collection of inclines overlooking Llyn Owgwen, encompassing Carnedd Lewelyn, Yr Elen, Carnedd Dafydd, Pen Yr Ole Wen.

Competitors will also need to take on the rough terrain of Y Garn, Glyder Fawr , Glyder Fach and Tryfan to complete the challenge.

The Oggie 8 boasts some of the best views in Snowdonia, with a beautiful panoramic landscape in every direction.

Although the route is tough and covers a large area, there are no compulsory scrambles in the route as it avoids Bristly Ridge and Tryfan’s North Ridge.

It's all part of an annual fundraising event for the Ogwen Valley Mountain Rescue Organisation , one of the busiest in the country with more than 100 callouts each year .

The team, whose patch covers Tryfan , the Glyderau and Carneddau, needs at least £60,000 a year to operate.

Event organisers are keen to make participants aware that marshaling will be provided by the Ogwen Valley Rescue Team over the course of the route.

There will be a check point on each mountain and at various points around the route that must be reached to enable route cards to be stamped.

The route From Bryn Poeth (SH674611), HQ of OVMRT, Capel Curig. Around of the 8 tops over 3,000ft in the Ogwen Valley - Carnedd Llewelyn, Yr Elen, Carnedd Dafydd, Pen yr Ole Wen, Y Garn, Glyder Fawr, Glyder Fach, & Tryfan. Avoids Bristly Ridge & Tryfan N. Ridge.

The event takes place on Saturday, August 10, with participants taking part in a mass start.

There are a number of different event categories - individual walkers can walk the course on their own, or they can bring a team of two or more participants.

There is also an option to complete the challenge as part of a relay, swapping at the half-way point.
