After a few minutes to regain my composure, we took off and I did my best to manage the pain. Marc had some Advil along that I took and that started to kick in about 30 minutes later.
It was a long haul back. We had another two hours in front of us and I was bonking. Somehow I thought this was a 10 mile ride so I had only packed two Powerbars. So for the next few hours I grimaced at the pain and tried to ignore the ache in my stomach. The last thirty minutes of ride was not rideable so I walked bits and pieces of it. In many sections the trail led right to the cliff's end making any sort of mistake a fatal one. Eventually, the end came and after catching my breath, I felt reinvigorated enough to ride hard back to town and give back my bike.
It was great trip and something I look forward to doing again.
PS Because my flight got delayed I spent another day in the area of Park City, Utah in a quaint town of Coalville. Because Marc has a decent motorcycle collection, we did a nice ride in the area in the early evening.
