I tried to run a marathon over a mountain....with my little dog

Nixon and I travelled to Wales to run in the Limitless Trails Beast of the Beacons 20 mile race. We were confident with the running part but not sure about the going over mountains part! Ended up being a good day and nice to spend some time outside my comfort zone.
