She ran 2.5+ when she was a senior and then slowed to 3.2 when she bulked up on weights. She was the fastest girl I ever timed. Too bad, but she wouldn't listen. 2.7 would be terrific.
I'm glad you mentioned this as my DD works out with some weights. I guess there's a line between the extra strength enabling her to run faster and the extra weight slowing her down. My DD also ran the 100m and 200m last year in middle school. Same thing, gets off the line very quickly, but then lags at the end. 200m is a lot of bases in softball!
