Good luck at the Monterey half! That's a really nice place for a road run, hope it's not too windy or foggy. I should do a real writeup for Castle peak, that would help me remember it too, I'm not sure if I'll do it again next year (because it may be too close to the 100 mile race I want to do), but it's a great one. I'm not sure about TRT- beautiful area for sure, I remember scoping out the 100 mile course and thinking that it had a lot of out and back on the tunnel creek fire road. Pacing Rio Del Lago Saturday night was a lot of fun; I hung out at No-Hands bridge for a couple hours in a light rain (got there a bit too early, but I didn't want to miss my runner, and I made friends and had good conversations while I was there), then my runner came in just a bit later than his goal pace, we met, and set off walking up the one big hill in my section of the race. My runner was a friend of a friend, a French philosophy postdoc living in Chicago with a sub 3 hour marathon time, named Nicolas, and that's about all I knew. That actually made it easy to keep up light, distracting chatter for much of the next 8 hours. I was there providing company, light (I have great lights, I do a lot of night running and take that shit seriously, most of the runners I saw out there had really marginal headlamps), nutrition reminders, and encouragement to run instead of walk on the flat and gentle sections. It was definitely pretty hard for Nicolas to run in the last quarter of the race, but his form was still good, and he tried whenever he could. He wasn't very interested in food, but I convinced him that it was his job to keep taking in calories, and I think that helped him feel better and better towards the end of the race. There was a low point at mile 96, the very last aid station, when he was for some reason thinking it would be 3.5 miles to the finish, but the sign there said 4.5. So a 3 mile mostly walking low, and then he smelled the barn (actually, he heard the finish line announcer), and ran (fast) the last mile and a half. 23 hours and 15 minutes to run 100 miles, i'm impressed. Lots of those hours were run in the rain, and there was plenty of mud on the course too. Pacing was fun. I'll be pacing again in 2 weeks, then looking for more opportunities to pace next year.
