I coach a high school girl who's running the mile 3 weekends in a row, at our league meet, the state meet, and then (hopefully) the All-State meet. There's not a lot I can really do about it, other than switching her out of the mile at the league meet, as she's a great miler.
So do people think three races in three weekends is too much?
No. That is the way the season rolls almost everywhere. Won't every runner in the All State meet be running the same sequence of meets?
Are you kidding me? Why would that be too much?
If they were marathons, I would say yes. For a teenager running a mile, not a problem.
The only "harm" is that at some point there will be a loss of peak racing ability/ fitness for the season.
I probably phrased that poorly, my main issue is running the mile 3 weekends in the row, and whether it would be better to do a different event the first weekend. I get a bit neurotic about training this time of year!
