50km: the entry-level ultramarathon

the one in which I run the Runamuck 50k, a beautiful race on mostly dirt roads in Vermont. Beautiful, but hilly. Historically, I have failed quite hard at distances longer than the marathon, but has my training in the past year paid off? I've started to incorporate more elevation and more speedwork, but will it be enough to tackle this "entry-level" ultramarathon here in the northeast? Will my nutrition strategy be adequate? Will my gear be enough? Follow me on strava for more:   / strava
