Kind of told you so there Bob a few weeks ago ..... the pack rides do seem to be aimed at the slowest of the pack so not great if you want a recovery ride at a decent enough pace to get the heart going.Made mistake of doing Pack Rumble in Jungle. So so slow. Much slower than advertised. Even though I was 5min slower than my best up KOM. I had to wait 6m for lead to begin to catch up. I became really cold and so rather than carry on waiting rushed off to start the jungle bit of the ride only to cramp a bit so bailed. It’s getting to be a habit.
