Love these poles. I borrowed a friend's set last year for a 32 mile event along the Jurrasic coast in Dorset. Knocked 1 hour 20 minutes off my time from the previous year without poles. Loved them so much I bought my own. Great quality, lightweight and comfortable to use for running and walking. I've taken them out on a few test runs so far and they've been brilliant. Looking forward to completing the same event again this year with them!
