For me 800m is probably the best interval distance for speeding up a 5k time. However I have a friend who has really got into marathon running in the past few years and he's become very quick in the 5k (19 minutes at age 59 !) so I suspect a combination of slower runs much longer than 5k (at least 10k) plus interval work is what you really need to run a fast 5k.
My very slow recovery from long covid continues - trying to do runs of 40-60 minutes at a low (zone 2) heart rate and build from there. Also started swimming again. It's a b*st*rd slow recovery, though - I expect it will be around 12 months from initial symptoms to getting back to the level of fitness I had pre-infection. (and I was triply vaxxed - be careful out there, folks).
