So my first ever 10km race is due to take place next Sunday. I've been trying to follow an Asics plan which was going OK at first but now seems to have gone crazy. On Monday I did 10km - felt great during & afterwards. Not a brilliant time but good for me. Thursday was supposed to be 5km - managed 4.5 - felt awful. Today was supposed to be 10km - last before next week's race. Managed 7km. I know I can do 10km but today my body just said NO!! I've got thyroid disease & about 6 weeks ago my doctor changed the daily dose of thyroxine. I think that may well have something to do with it. Wonky hormones are the very last thing I need right now. That Asics plan is telling me to do a 5km jog on Monday, a 5km on Tuesday ar 'race pace', another 5km jog on Thursday. If I do that I'll be dead on my feet - they don’t seem to factor in working full time & life do they? I think I'll stick to my usual Tuesday & Thursday 5km(ish) then give the 10km my best shot on Sunday. I've pretty much accepted I'm going to be one of the last to finish even looking at last year's finishing times. I still can't decide if the Asics plan is a good or bad thing. It does give a bit of structure but the psce is too high - which I can't seem to adjust - & the distance for the total schedule seems too high for a 10km.
