I think I've tumbled so far down the hill that I can no longer see the top. 18 minutes down at the first CP on Jura last weekend, only just within the cutoff and going backwards. No problems there on the last 17 Juras - I'm at a loss to explain it, as far as I'm aware I haven't had Covid and I've done some decent training.
On a related note to the posts above - I don't drink either and have never had any hassle or Mickey taking from other fell runners - quite the opposite if anything.
