Yesterday I ran in the Christmas Pudding 10k “Challenge” (as the Brackla Harriers like to call it). As you can see, it was a proper cross-country 10km race with far too much sand (the race is infamous for its start up the largest sand dune in Europe). In lieu of a race report I’ve included a screenshot of my vitals during the race. The red line is my heart rate, the brown line the altitude, and the blue line my running speed. You’ll notice that my heart rate is rather rapidly elevated from the start – that’s the sand dune.
