Try it and find out.

I find when I get really winded I experience symptoms but I am not sure if it is necessary to get my heart rate up as much as I do at times...at 57 I still compete with myself.

1. Try a little run first.

2. Try it on a Friday afternoon when you have the weekend to observe.

3. I still can't run without an incline, the incline makes less impact and no headache. Flat ground equals headaches.
