I tested myself a few weeks ago – to get a baseline. I ran 400m on a track in 1:30. I thought this was excellent considering my build and that I had not run in years. Credit to other forms of exercise!
So, I set out to keep my 400m development. I marked off the distance on my street. I ran in the rain. I loved it.
One day, during one round of 400m, I was moving along and my calf muscle freaked out. No pain, it just seized. It cramped into a knot. I had to hobble home.
I have been treating the affected leg: Graston Technique (google it), massage, ice, NSAIDS, flexibility work…
My research took me to the “Pose Method” for running. I think the major problem for me is form. I never got winded – just the cramp. Run a lap – get a cramp.
Anyway – I have found that the CF people Teach this method. There are a ton of good drills in the book (supposedly). I also note that when I search for it in Amazon and read the list of related books, Total Immersion is in the list. This book is enough of an endorsement for me.
Sorry , I didn’t mean to blather on your post. This is a current issue for me.
