And to answer one of the questions mentioned by @Nate_Pearson and @Jonathan in that old podcast you guys have the old national championship course in your own backyard. Xterra Nats were held in Incline Village when I first started up and by the time I was ready to make a run to go there, they moved it to Ogden outside salt Lake City. The Xterra Lake Tahoe course goes up the flume trail and around Marlotte lake and back down to Incline Village.
This is longer than an average course though, what would be considered a “Championship” level race with the pros finishing the whole thing in around 3 hours
