800m training after injury

As long as your injury is healed completely, then you could very possibly do this. You should talk to the coach at your college, and ask him what he recommends for an 800m runner coming back from a serious injury.

For a sub 1:55 here are some generic criteria.

You'll want to max out at 50-60 mpw.

You'll want to run at least 1 top speed workout each week.

You'll want to do one longer interval workout each week.

A long run up to 10 miles once a week.

You should run twice a day most days.

You should do lots of drills and plyometrics.

Hit the weight room 1-2 times a week focusing on very specific motions to translate to running.

The actual plan would vary depending on where you are during the season. For now I would focus on just getting out and running 6 days a week maybe for a mile or two, followed by some easy strides on a soft surface like grass. As you become more confident in the state of your injury, you can increase the mileage gradually, and start throwing in top end speed work, and then develop a periodized plan for yourself. Most important is staying consistent and injury free.

Good luck!
