In reply to kevin stephens:
I think choice of partner is key. If both you and your partner are at relatively low risk of having Covid (eg WFH / retired), that's a good start. If your prospective partner or their other half works in a hospital or care home, that's going to be high risk, so probably inadvisable to climb with that person at the moment.
Of course we should do the best we can to maintain SD but no need to go to extremes. So no sharing cars or handshakes/hugs and stick to single pitch. If you want to be purist about it, use separate gear and do separate routes, so the leader strips the route and the belayer leads another route - perfectly possible on quiet crags.
Personally, I'm not too concerned about using the same holds and gear - it's outdoors, there is sunlight, rock is rough which is not conducive to the virus hanging around. I do avoid putting gear in my mouth. Harder not to do it with rope but the two climbers can easily use different ends of the rope to lead. Came across one gate on Monday and used the clipstick to open and close it - again, the risk is probably low but many walkers had used that gate, so it's going to be higher risk than holds on a route which only I and my partner had been on that date.
I'm more concerned about picking up Covid from a door handle in my apartment block as several hundred other people live there, so I'm very careful about using a glove and/or washing hands. Same at petrol stations.
The way I see it, I have a kind of 'Covid risk budget'. Where possible, I will do things in a way which use up as little of the budget as possible. For example, not going out of the flat more than once a day, not meeting friends in person, being very careful about hand hygiene. That way I keep my budget to spend on climbing days out but again I will take sensible precautions.
At the end of the day, it's a personal choice. If it doesn't feel right to you, you don't have to do it.
