This past week (5/18-5/24) I ran 55.64 miles in six runs including back-to-back long runs of 15 and 17 at the weekend. The week before (5/11-5/17) was a cut back week of 33 miles in four runs with a long run of 20 miles on the SVT at the weekend. The two weeks before were 47 and 46 miles respectively.
An interesting thing is turning up. Around 8 miles or 1:30, whichever comes first, I start feeling really woozy and wobbly. I've also noticed that both my hands, the finger tips really, get quite numb. At first I thought the woozies were simply a fueling issue and started gelling a little earlier than I normally do (at 5, 10, 15, and 20 instead of around 7, 13, and so on). But that did not stop the problem. I eat well the day before and started the run well-fueled. That also did not help during the long runs (it is a little less noticeable on the short duration runs).
What could this be? Some theories:
- I may be eating a lot (not losing or gaining weight at this point) but maybe not the eating the right things?
- The gels I take, Gu's, may not have what I need during the run. They are just carbs and it could be that I need some protein
- Blood Iron deficiency? (Won't know until I get tested in a bit)
- Body shifting from immediate fuel stores (gels, etc.) to stored fuels. I remember reading something in Peak Performance about this happening (and being a good thing too). Time to look at my archives
- This is all in my head
In any event. This has me scratching my head. Could this all be in my head? It made my long runs this weekend a bit interesting.
34 Days until Seattle Rock N Roll Marathon.
