> PS when I got my permit for the run last year, 2 guys had picked up a permit the previous day for a single day 42 mile run on the same route. Apparently the Inyo computer doesn't allow entry date and trail crest exit date to be the same which caused a few problems...

Ultrarunners are truly animals! Actually, since they were day hiking, all they needed was the Whitney day use permit. No permit required to day hike (or run) in from Horseshoe Meadows. Only permit required is for the Whitney main trail exit. Those Trail Crest Exit permits are for overnighters, so the day-use permit would be good -- doesn't matter that they started their day on a different trail head; once in the Whitney Zone, they were the same as day hikers.
