I did a 26 mile ride today on the West Samammish River Trail connecting to the Burke Gilman and the back. The ride was great, I fought a light headwind to start (6.5mph) but warmed up after 6 miles or so and the ride went smoothly. My heartrate was happily in Zone 3 for the entire ride so I feel very good about that. If I keep these rides up on the weekends I will be in shape for the STP without any issues.
