I have just started running for the first time in several years. And when I say "just started" I really mean the "just" - I've done two runs at the very start of the couch to 5k programme (running 1 minute walking 1.5 minutes, repeat 8 times).
I used to be an OK runner, but I got very ill and wasn't able to exercise. I've gained a load of weight and lost just about all of my muscle tone, strength and stamina in the interim. So I am really unfit!
I'm finding the exercise very beneficial, physically and mentally. BUT I am shattered! I am literally falling asleep at my desk this afternoon. Yet I've slept really well the last few nights - my usual hours of around 11 - 6.
I can't believe such a small amount of exercise has done me in this much! Is this normal? Will it settle with time? Any tips on how to cope through it?
