I graduated last week, which was a bit of a flat spot. It wasn't the run I had planned, and it wasn't a good run. I've had a bit of a cold and the like for about a week, and am pretty much over it.
On Sunday I went for a run in the morning, and to be honest it was my worst run yet. I didn't run for 30 minutes without a rest, which is the first time ever. I felt really out of sorts with the whole thing. Later that morning we met up with friends and walked around a reservoir which is 5 miles (no stretch for me at all, used to 15+ in a day!). Then in the evening I cycled over to the next village and back (6 miles round trip). So, probably more exercise in one day than I normally do.
The thing is on the day after Monday I was so tired. Positively run down, flat batteries and all that. My legs ached in a kind of 'flu' / tired kind of way. I had an hour and half's kip straight after work, then back to bed at 8pm. Knackered, slept all night. I can't believe I am still suffering from this cold, but then my wife said 'Are you eating enough in relation to the exercise you are doing?' I guess this is the classic question to ask your GP. Has anybody else experienced this? It's left me really rather flat.
