1) it is a pretty common name- Are you sure all the run times are the same person?

2) sometimes I run local races with friends, with my kids, with my husband--- some women run pregnant, post-partum with and without strollers. So running times can be all over the place.

Not sure what the outcome of the Tonya Harding/ Nancy Kerrigan situation will be here-but there can be lots of reasons for variability in run times that don't mean anything.
