Hi excellentjeni,
Great job! Congratulations on your 7 mile run! You should be very proud!
Your calve pain may very possibly be due to the cement. Pounding the pavement really can reap havoc on the chins and calves. There's not much you can do about the cement, so the best advice I have for you is to make sure that your T-shoes are in great condition, providing maximum cushion and support. It may not be a bad idea to visit a specialty store that looks at your gait, arch, etc. and get a shoe fit specially for your foot. Additionally, do some warm-up laps (3-5 minutes) then stop and stretch. Stretch both the calves and the chins (the back and front of the lower leg). Both the muscles lining the chins and the calves need to be properly stretched, as they are opposing muscles. Point and flex the foot, off of a curb or other elevated surface, etc.
If your calves continue to hurt, you're going to have to cut back on the distance, as well as ice them each time after you run. Take a couple of IB profen before you jog, if you can. Again, if you continue to experience pain, try using alternate forms of cardio, intermittently between running.... jog a mile or 2, jump on a stationary bike, then on an elliptical, etc. You may have to keep it inside?
I know you'll do great! Just keep up the hard work!
Yours in health,
Kelli
