Many changes have been made to the Tierra Bella routes this year! There are two new reststops and five new routes to choose from. We have something for every rider.

33M (32.2 miles, 742 ft)

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.

Flatter 100K (55.4 miles, 1882 feet)

This year we have three 100K’s to choose from. This is the flattest, with no major climbs. It 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.

Hilly 100K (51.4 miles, 2398 feet)

This 100K starts off with the traditional climb up to Gilroy Hot Springs followed by a descent of Canada Rd. Then you loop to San Martin before heading over Day Rd to Chictactac-Adams County Park. Follow the blue arrows.

Very Hilly 100K (63.9 miles, 4548 feet)

This 100K climbs up to Henry Coe, but without having to do a hundred miles. You will loop around to San Martin on your way there. Returning, you go to Chictactac-Adams County Park and straight back to Gilroy. Follow the pink arrows.

100M (95.4 miles, 6674 feet)

This century ride contains all of the options from the 100K 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.

There are also three short-cut options on the 100M route, if you want to ride more than 100K but not a full century.

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.

Starting Location

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.

Starting Times

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.
