Many thanks for this; I've been a hillwalker for decades & was wondering how to cope with walking in this crisis re walking I was treated for cancer in 2018 & walking helps enormously following that, & has always been good for physical & mental health.. Exercise incl walking is encouraged for cancer sufferers and survivors; we also have to take a lot of care over Covid 19 susceptibility though. I'm reliant on public transport when I don't do circular walks from the house, but decided to avoid it if at all possible during this crisis, reinforced by govn guidance.. The trains I use are also v crowded with walkers at peak times eg w/es. Also, sadly, I'd realised I should avoid the pub stop(s).! I'm happy walking alone & have done so for decades; I've researched & trained re navigation so know what I'm doing pretty well, take all necessary precautions incl carrying 1st aid, spare warm clothing, food & drink, mobile & am registered to text MR if signal fails. HOWEVER it's v useful to be aware that ME c/b depleted or even non-existent; I hadn't thought of that but it's obvious of course, as is the point about the risk of putting more pressure on an NHS already stretched with Covid 19 crisis. Thank you! Take care
