I stopped for 2 weeks and then after 20minutes in first session back the stabbing pain came back. That is when I decided to go to the Doctor.
My Doctor here in France. He is a Sports Doctor too. He told me that I increased my training rapidly or increased speed work. Turns out I was doing speed work on the track.
Result ..."<span style="background-color: #eeeeee; font-family: 'Trebuchet MS', Trebuchet, Arial, helvetica, sans-serif; text-align: left;">strengthening and enlarging of muscles behind the knee trapping the artery and restricting blood flow to the calf - resulting in sharp pain every step"...
Normally occurs on one leg only. The weeker one. Common problem.
He told me NO running for 5-6 weeks. Then start with 2-3 half hour sessions only. Then GRADUALLY work further and harder. The problem was I pushed it too hard too soon and my body could not adjust in time.
I may do some very gental cycling (with no speed or hard gears). He highly recommends swimming.
Well, 2 weeks to go and I am feeling great. Loving the swimming. The Cardo is just awesome training. I am pretty sure my breathing and stamina is going to be at a new level when I get back to running.
Jim, I have the same problem and my Doctor here in France, a sports Doctor explained exactly as you have. Increased trainging, especially on track, muscle expands etc. Prescribed rest (no running for 5 weeks) and swimming pool too. I do some very light cycling too and feel much better. Another 2 weeks to go and I may start with 2-3 half hour runs only then gradually pick it up after that...
My cycling helped me with leg sped and strength. It made an improvement on my running. BUT, I nowswim as much as possible and the difference is enourmouse. I find my core muscles and breathing are much more comfortable at a fast pace. In 6 months I took 20minutes of my Half Marathon time and 15 minutes of 10km. I am not a triathlete. I just read quite often how good swimming can be for overall strength and breathing. That last 5km when it hurts... Go swimming!
Somehow, I eat much more when in training. When injured I tend to drink too much coffee and it is perhaps that that makes me eat less. Funny because when I am in good form I can't stomach the thought of drinking coffee. I just naturally want something fresh.
