Up and Under Trail Running

Welcome to the Trail and Ultra Running section of our website. Up and Under in Cardiff has been supplying fell running specific footwear for years, but has expanded into the wide ranging and glorious world of trail running in the past 10 years. We have a close working relationship with a number of trail and ultra race organizers in the area, most notably Run Walk Crawl, Ridge Runners and Up Hill Down Dale and have therefore expanded our range to cover Ultra Running products that can help you race on all terrains, through day and night, for 4 seasons of the year.

A lot of our core clothing ranges and equipment such as headtorches, first aid kits, whistles, etc. are equally appropriate for trail-running so don't forget to take a look around those sections or use our search if what you need isn't immediately obvious within this part of our catalogue.

We select the best trailshoes, packs, poles, vests, torches and clothing from baselayer through socks, shorts, tights and insulation to windproof and waterproof shell, hats and gloves and we have what you need for all your fell and trail-running needs, all carefully selected by our staff with insights from Run, Walk Crawl to suit you. It's all from the best brands, but see the quick links below to rapidly access some of our most popular. It's also worth having a browse outside of running through our Odlo range for extra warm quick drying, high wicking, lightweight base and midlayer clothing and everything beyond.
