| Hi Ryan.
I've been preparing myself to run a half-marathon which is 13.1 miles so I've been getting some practice at this. You don't say when you need to be able to do this by, but the best way to work on this is to gradually work your way up to that distance by working out 3 times a week with at least one day of rest and recovery in between workouts.
Test your blood sugar before the workout, and test it when you're done so you can start charting the effects. I'd suggest that to start out that you simply run at a pace where you could easily talk out loud to yourself, or what's called a conversational pace. If you need to slow up into a walk, do so, and make your first goal to gradually get to where you can run that easy pace for 30 minutes without any walk breaks.
Good luck. It can be done, and it's great to make exercise a consistent part of your life. |
