In short course, PEAK swimming’s Benjamin Ho holds the 13-14 National Age Group Record in the 200 backstroke. Now, just a week into his long course season, he’s taken down Ryan Murphy’s record in the 100 long course race with a 57.39 at this weekend’s PASA Race for Earth Day A+ meet in northern California. The old record belonged to the National Team’er Murphy from 2010 in 57.76.

This swim comes after last weekend when Ho missed the record by just .11 seconds, and it knocks Murphy completely off of the 13-14 National Age Group Record books (though he’s still prominently featured in the 11-12 and 15-16 lists).

Ho could take another shot at lowering his record next weekend before aging up in early May. This was his only swim of the two-day age group meet; last weekend he swam a 200 backstroke as well in 2:04.87, which is pretty far off of Aaron Peirsol’s 1998 record of 2:02.78.
