I received these poles just in time to use them on the 2022 HardWolds 80. As a VET60 and relative novice at Ultras I need all the help I can get, and these were brilliant. I've used a pair of adjustable poles from Fizan for years when I've been mountain walking, but I wanted some which were easy to fold away and store on my running vest when they weren't needed. When I watched some reviews on YouTube and saw the price, I decided these were the ones. And they didn't disappoint. They were so good and light that I only packed them away once for about 15 minutes - the rest of the time they helped to power me along in under 20 hours (just)! So big thanks to Harrier and their excellent poles (and service).
