Sea Otter Classic/Thule Adventure Race

  • Laguna Seca Recreation Area, Monterey, April 12-15

Every year, thousands of bike lovers converge on the race tracks at Laguna Seca for a celebration of all things cycling. The Sea Otter Classic has become an early-season rite of passage for crankheads of all stripes, who come to test their spring legs, check out the newest gear, drink beer and rub scraped-up elbows.

This year, the event is expanding to fold in the growing world of adventure racing. The inaugural Sea Otter Classic Thule Adventure Race will feature kayaking, biking, running and navigation.

Other events guaranteed to induce an accelerated heart rate include the SRAM Pro NRC Road Circuit Race, the Mountain Bike Endurance and Mountain Bike Gravity events, and spectator favorites, the SRAM Invitational Dirt Jump Contest and the SRAM MTB Super D, a hybrid of downhill and cross-country racing.

At the center of the action will be the massive Sea Otter Village and Expo, home to nearly 300 vendors. Nearly 10,000 professional, amateur and recreational athletes are expected over the long weekend, as well as 50,000 sideliners to cheer them on.

Passes are $10 per day or $30 for all four days. Kids under 12 are free. For more information or to register for an event, visit or call 800-218-8411.

Whether you’re considering a trail run for the first time or are an experienced ultra runner, Pacific Coast Trail Runs promises a rewarding experience in a beautiful environment. Events are held nearly every other weekend and offer course distances from 8 kilometers to 50 miles in scenic, challenging terrain in and around the greater Bay Area.

PCTR is known for creating spectacular, well-marked courses and hosting aid stations that make runners feel like Norm in “Cheers,” only much less sedentary. The growing lineup at the start may be due to the non-competitive atmosphere – the emphasis is on personal achievement and awards are given only to the first male and female finishers – or it could be due to the goodie-laden picnic tables at the finish.

Several races in the series have sold out already so runners should book now for events through the rest of the season.
