Dunnerdale today, 5m/1800'. Just had to start running and see how it panned out; i was slow on the first climb, lacking a bit in the middle section, feeling it a lot by the top of CP2. I'm not burning out really fast and i'm getting more 02 in, but it translated to a bit of a stinker, 4mins off my PB which is the sort of speeds i was running 10yrs ago.
