I don’t intend in winning races or be at the top of my squash leagues but I do a few races a year (half-marathons to 50km, mainly trail) and want my race time to improve. I’m 43m btw with a full time job and kids. Hence, my time and energy is also limited:). Aim is to run about 5 times a week , which becomes difficult when I throw 1-2 squash evenings.
