The Growler: 138 miles, 14,000 feet, and ten hours to hold the whole day together
Levi's GranFondo starts in Windsor, California, on Saturday, April 24, 2027. The competitive Growler route covers 138 miles and gains 14,000 feet across Sonoma County's wine country, redwood canyons, King Ridge, and the Geysers, with age-category placings and a 1:45 PM course split at Dutcher Creek.
For the rider chasing an age-category result on nine to thirteen hours a week, this twelve-week Alpine-Fondo plan develops repeated climbing power, front-group economy, descending speed, and the fatigue resistance to keep racing deep into the Geysers country.
INSIDE THE COMPETE PLAN — 9–13 HR/WK
Includes zone-tailored structured rides for your devices, built-in strength with video walkthroughs, heat protocols for when your race calls for them, peloton skills workouts, and nutrition and hydration guidance.

Hey, I'm Matti. I spent 11 years at TrainingPeaks, where they trusted me to teach coaches how to coach at TrainingPeaks University. I raced Amateur Elite with Rio Grande Cycling Team and podiumed my age group at Unbound 200 in 2026. I have a degree in biology and exercise physiology from St. Olaf. I'm also a middle-aged dad of three, so I know training doesn't happen in a vacuum. I help gravel riders get stupidly fast without becoming the person who brings a food scale to a party
