Back in the day, Sailor Tracey Edwards (former teenage backpacker!) and her team aboard 'Maiden' doing the Whitbread Round the World challenge, inspired me to make sure I got out and actually did stuff. I recall watching the catch up programme every Saturday morning and following all the teams progress. This indirectly led to me doing John O'Groats to Lands End a couple of years later still in my teens (although nothing to do with boats!)
More recently at a time when I needed a lift I was switched on to the Lakes via Julia Bradbury's walking series. Whilst she might have turned herself into a brand these days.. those simple early series walking the fells, inspired me up and out again.
On the climbing front - Lucy Creamer, and Hazel Findlay inspire me - not really to climb, but to make sure I challenge myself enough in whatever endeavour I'm doing.
Cathy O'Dowd - mountaineer who took part in the Mazeno Ridge expedition a few years back.
Jenny Jones - Snowboarder, who is now a really good presenter, and has done some good pieces for Ski Sunday recently.
