As it says on my C25K page, I’m not starting from scratch here. Having spent three months gallivanting around New Zealand, Fiji and Australia, I’ve been doing some pretty spectacular practice walks.
Back when I was in hospital, I was weak, but could walk around a little bit. By the time I left, I could walk pretty much normally, but stairs were tricky. A few weeks later, stairs were all good, but I tried to run for a bus and that didn’t go so well.
Running a half marathon nearly killed me, and that’s only a little bit of hyperbole.
A year ago today I attempted the Hackney Half Marathon and, to cut a long story short, found myself first with heatstroke and then with rhabdomyolosis, or rhabdo.
Caused by muscle exhaustion and heat (in my case anyway), rhabdo leads to a breakdown in muscle tissue and causes the release of a protein, myoglobin, into the blood. This kind of toxin would usually be flushed out by the kidneys, but myoglobin cells are too big for that, and lead to the kidneys becoming clogged up and ultimately – to put it politely – broken.
