1. I'm coming back from injury
2. I'm carrying too much body fat and my legs aren’t used to the extra 5-8lbs
3. I've put on some muscle mass on my legs which makes them heavier each step
4. I've not adjusted to the heat increase that is summer in dc
5. I've not adjusted to the humidity increase that is summer in dc
6. The cycling is taking a lot more out of me than I realise or will admit to
7. The mileage I'm running is taking a lot more out of me than it would have done pre-injury
8. After cycling around loads running just feels slower
9. I've lost all efficiency in my stride and form
10. My body has lost the ability to recover quickly from workouts so I'm still not recovered from last nights 6mile run or this mornings 4mile run
there might be more... or some above might be rubbish (the first one doesn't really make sense as the rest all all products of the first point... stupid hugh)
Fact and science? Stuff made up in my head? Just ran 10mile outside at noon in 85F and it just felt much tougher than it should. I can only hope that i get some speed back in my legs and long runs in the next three weeks (the amount of time I've scheduled ahead and given myself to get in shape before I start hitting the track and doing quality workouts again and using a stopwatch properly again).
