Totally!! 15s gets you big returns at many ultras! She might consider the 30mi option at the SRT Run/Hike
in September. It's a walk-fest for many, anyway. 15s got 12th place (of 30) last year. Just need to do them for 7.5 hours. ;) There are
appropriate joggy bits, I'm sure.
, no pressure, and no rush.
