rode over Dartmoor a couple of days ago. Died on the way up. Just died. Coughing up bits of lung that I haven't used for ages. Didn't have a heartrate monitor but it would have exploded. Walkers passed me, I passed them, then stopped and they passed me again. Would have sold my bike at the top for a quid. Pushed up a lot.
Really enjoyed the ridge riding, but was still slow on the gentle ups as the first steep climb had taken it out of me. Cut the ride short as would not haver made it all the way round.
Basic fitness is okay but not great. Am guessing I just need to ride more. Or buy a scramble bike, or move to the Alps and do uplifts only.....
