I really enjoyed running on the dirt trail along the river in Uppsala in the early morning when I was there for ACL in July, so I decided to explore the Peninsula trails when I got back, which with their slopes would help my conditioning for uphill skinning in the coming backcountry skiing season. I started with the popular trails of the Arastradero preserve, but I wanted more. First, I needed proper trail running shoes. I got some poor advice at REI for my first choice, but the staff of ZombieRunner hit the sweet spot with a pair of Brooks Cascadia 5. I loved these shoes on their first outing, 6.25 miles this cool morning at Arastradero. I also got Trail Runner's Guide: San Francisco Bay Area by Jessica Jage, ordered at Kepler's. It's a well-written, detailed guide. I did the Long Ridge loop (mostly, I missed one of the side trips) last Sunday, and I'm now studying options for tomorrow. I can't believe I've lived in the Bay Area a total of over eight years (in two widely separated chunks) and that only now I've started to taste the delights of running on these cool golden hills. Since I've started, I am looking forward to my Saturday and Sunday morning runs almost as much as look forward to a ski tour in the Sierra. It's addictive, I just hope my worn-out knees don't have other ideas.
