I keep telling people to click on my blog links so I earn a massive 4% cashback to help fund my next adventures and to encourage that, these are links from the best companies to buy stuff from. I might even buy you a beer if you use them!
First the bike shop with the biggest range of kit available, always my first port of call;
Not the biggest range but normally the cheapest place for boring but always needed kit like group set components etc;
These guys have a good range of outdoor kits and have some good sales, best of all they probably have a store near you;
Sports direct might look a bit out of place here, but click on the link and you will see they have some great quality kit at dirt cheap prices, for example Terra Nova tents are oftern reduced here;
Wiggle are the biggest name about ofr running and biking and have a huge range;
Evans has a great range of complete bikes and good starting point for people new to the sport, they have loads of stores too;
