Blood test shows a serum ferritin level of 9 ug/L. “Normal” is 12-250 ug/L - a pretty big range, if you ask me (which of course the medical profession will do imminently) - with anecdotal evidence suggesting that many runners notice a drop off in performance if they go below 50 ug/L. Last time I had bloods done, back in June, I was at 32 ug/L.
So, a bit of a relief. Not only do I have a valid excuse for sub-par racing over the last few months, but it’s one that will (hopefully) be easily correctable. At least I have a literal note from my doctor to explain a crap run at the XC on Saturday!
