Hi everybody
Don't post often but wanted to share this.
I started C25K a year ago. Did a 10km in October. Due to holidays and slightly gammy knee took the rest of the year off.
In January I started again. I was making steady, if slow, progress. Times were a bit quicker, distances were longer.
Then at the start of May I started going backwards. I lost 15-20 seconds a KM (and when you are as slow as me that's a tragedy) then found the running harder and harder. 10km would see me virtually crawling back home and I completely bu#@ered up a race in Oxford which was soul destroying.
Tried hill work (nearly killed me), track work with local running club (embarrassing).
I couldn't understand why I was actually getting worse as I had no injuries.
Last Monday I went to give blood (for first time in years) and I guess you can tell what's coming. I am anaemic. Quite severely actually.
I had no idea. Now I am armed with iron supplements and hopes I might finish the Oxford Half before the 3 1/2 hour cut off!
So, if you see a marked decrease in performance (as well as overall tiredness and breathlessness) it could be your iron levels. Don't soldier on like I did. I've wasted two months. On plus side doc has said when iron levels return to normal I'll be off like a rocket (he obviously hasn't seen me but there we go).
