RideBikesWales Strava club - we love to ride bikes, road, mountain, cross, gravel, TT, and occasionally Triathlon too.
Our club rides are run on an ad-hoc basis, mostly off-road, suited to MTB, Gravel or Cross bikes. The rides are sociable and fun and usually include a cafe stop.
Additionally, you can join Nic (our part time mechanic - he's also a qualified BC coach and ride leader) who runs the #TuesdayTraverse, a gravel / cross / MTB ride, most weeks, from Rhiwbina, in Cardiff - ride details on https://www.strava.com/clubs/Veloadventures
