Many changes have been made to the Tierra Bella routes this year! A selection of four routes have been chosen for the Tierra Bella this year. There is no longer a route called “100 K”, but instead we have 33, 55, 77, and 100 miles to choose from. Each route doubles the amount of climbing of the one before it: 843, 1,680, 3,383 and 6,803 feet. We have something for every rider.
If you have not ridden much over the winter, we recommend this flat route through Gilroy and a big loop out to San Martin and then over to Chictactac-Adams County Park. There are lots of new roads and scenery to experience on this shorter route. Follow the yellow arrows.
This route starts with a loop out to San Martin, then continues north to Coyote Valley Open Space Preserve at the halfway point. Heading south you climb up Willow Springs Rd, past both Chesbro and Uvas reservoirs to Chictactac-Adams County Park. Follow the green arrows.
This route starts off with the traditional climb up to Gilroy Hot Springs followed by a descent of Canada Rd. Then you loop out to San Martin, before continuing north to Coyote Valley Open Space Preserve. Heading south you climb up Willow Springs Rd, past both Chesbro and Uvas reservoirs to Chictactac-Adams County Park. Follow the blue arrows.
This century ride contains all of the options from the routes. First you climb up to Gilroy Hot Springs and descend Canada Rd. Then you go over past San Martin before starting the challenging climb up to Henry Coe. You next head north to Coyote Valley Open Space Preserve at mile 70. Heading south, you climb up Willow Springs Rd, past both Chesbro and Uvas reservoirs to get to Chictactac-Adams County Park. Follow the orange arrows.
We use “Ride With GPS” mileage and climbing totals. We will provide RideWithGPS downloadable routes to registered riders as the date approaches. These routes may be used off-line with the RideWithGPS smartphone apps and other GPS units.
All rides start at Gavilan College's main campus, 5055 Santa Teresa Blvd., Gilroy, CA, about 35 miles south of San Jose. If you are heading south on Highway 101 from Gilroy, turn right on Castro Valley Rd. and right on Santa Teresa Blvd. to the north entrance of Gavilan College. Look for a sign to Gavilan on Hwy. 101 just south of the Monterey Rd.exit.
If you are approaching Gilroy from the south, you will not be able to turn left from northbound 101 onto Castro Valley Rd. due to the median barrier. Continue north to the Monterey Rd. exit where you can loop under 101 and head back south to Castro Valley Rd.
Please double-check your GPS directions! Gavilan College recently added a second campus on Bailey Road. Tierra Bella starts at the Gilroy campus.
There is no need to physically check in. If you have NOT received a registration packet in the mail, please come to the Help Desk in the Student Union/Cafeteria and we will assist you.
