The 24th annual Hinte-Anderson Trail Run 50K goes to the starting line in Susquehanna State Park March 24 with a field of 512 entrants. As has been the case in recent years, the field reached its limit long before race day. Among the top entrants are Glen Redpath, 56, of New York, who has won 13 of the 70 ultramarathons he has run in the last 10 years. He won the 2007 HAT Run. Kristen Eddy, 41, of Virginia, returns to defend her women's title. She won in 4 hours, 48 minutes last year. The race begins at the Steppingstone Museum at 9 a.m.
