In late May site user Sam Bradshaw (username sam-brad) aims to climb 24 peaks in northern Snowdonia within 24 hours to raise money for Macmillan Cancer Support.

His route loosely corresponds to the course of the Welsh 3000-ers, taking in the principal summits of the Carneddau, Glyderau and Snowdon; but several smaller outlying peaks are added too, to make it a much longer and tougher challenge. The route incorporates: Tal y Fan , Drum , Foel-fras , Garnedd Uchaf (Carnedd Gwenllian), Foel Grach , Yr Elen , Carnedd Llewelyn , Carnedd Dafydd , Pen yr Ole Wen, Tryfan , Glyder Fach , Glyder Fawr , Y Garn , Foel Goch , Mynydd Perfedd , Elidir Fawr , Moel Eilio , Foel Gron , Foel Goch , Moel Cynghorion , Snowdon (Yr Wyddfa) , Crib y Ddysgl (Garnedd Ugain), Crib Goch and Moel Siabod ( Carnedd Moel Siabod according to the OS - if no one else). He'll choose the exact day of the trip based on the weather.

'My mum was diagnosed with bone cancer having not long recovered from breast cancer' Sam tells us. 'Macmillan have been very good to both my Mum and my Dad in this difficult time, so I want to do something to help.'

Sam, an outdoor instructor and keen climber, grew up in the area and knows all the hills well - but he's never tried to link them all.

'I'm not too worried about endurance as I am relatively fit and I'm training hard' Sam says.

'I have been mainly focusing on lots of running and cycling, and getting out on the hill whenever possible. It's hard to fit hill days in as I'm working and caring for my Mum, but I am managing to get out for at least one day and one night every week.'

'Physically I think going over Tryfan and up onto the Glyders will be the hardest bit of the challenge, but I have done it many times and as a climber I love Tryfan so I don't think this will be a problem.'

'I think the toughest part will definitely be the mental side of it, having to keep going when I'm tired and alone. Mentally the hardest bit will be crossing the Carneddau at night as I think it will be very boring and lonely; also the last slog up Siabod with tired legs and a tired mind will be hard!'

'My dad and my fiance will be supporting me with food and drink at the road crossings, and they'll probably walk some of the legs with me too.'

Sam's current fundraising target is a modest £500, though he hopes to better this. See his Justgiving page for more.
