Hello!
It's been a while since I've been on HU, so I thought I'd post an update.
I found that 6k was too much for me at the moment (seemed OK when I was running but I was shattered the following day). Anyhow, built up to being able to comfortably run 4k (slowly), on Monday, Wednesday & Friday, on Saturday, helped out at Parkrun, worked out in the gym, went ice skating and broke my wrist.
I've managed a couple of visits to the gym since then, using an exercise bike and then a running machine to try to maintain fitness. So far I've avoided running outside with my arm in plaster because I'm worried about slipping and doing further damage (I'm aiming to get to almost full strength for the ski trip on 1st Feb).
I'm thinking of trying a 4k tomorrow afternoon when the forecast says it should be dry.
