Gerry North (won the National XC) maintained that it was leg speed above all else that mattered. Sort out the cadence first and then increase the stride length by strength training.
Have been having a read up about muscle physiology, mainly about why having a low blood calcium level makes me run so crap.
Seems that when muscles reach their greatest length, its also when they are at their weakest. So there's one reason to increase range of movement, but also to put that range of movement to the test.
It could be that speed training does more than increase fitness. It may be necessary to run at speed simply to get to parts of muscles that slower paces cannot.
As for my blood calcium levels. Technically its too low. Sometimes low enough to get cramp. I increase it by chomping a couple of thousand grms of supplements each day. On Saturday I tried a weights exercise 75 minutes after 1000grm plus a vitD. Surprising result.
With the leg extension exercise that I sometimes do, I get to 30 reps and I'm tying up. 60 was about the limit before I get stopped.
This time I got to 30 reps, nothing! 60 reps, nothing. Went to 100 and stopped out of choice. I do one leg at a time. 100 with the other leg too.
On Sunday I went running and it wasn't a strain. Could be on to something, hopefully.
