Sublime run. Boulder will always reign supreme for best trail running. Wasn't really feeling that nostalgic for it until this. Perfect mix of scrambling, flowy, and technical singletrack. I'm really really going to miss running in September, hope I don't lose too much fitness. Scrambling seems to still be in the muscle memory - I had 17:25 on my watch and 14:01 on the segment is three seconds off my PR for Freeway so call it a tie. 28 minutes from Gregory to the top (which happens to be exactly one mile apparently). Maybe I had never actually been to the high point of Flagstaff - could that be? I haven't truly flown down cruiser trails in so long it felt incredible.
