GENERAL RIDE RULES

  • Obey all California Vehicle Code rules.
  • Personal SAG vehicles ARE NOT ALLOWED.
  • All riders who abandon the event must call the emergency number located on the bottom of the route sheet.
  • All riders must check in with the time-keeper at each rest stop or be disqualified.
  • Required by law under CVC 21201 are lights and reflectors. Before sunrise (7:10 am) and at sunset (6:42 pm) cyclists must have a front headlight (white) visible from a distance of 300 feet. A rear red non-blinking taillight visible from a distance of 500 feet and reflective ankle bands on both left and right legs that are visible from a distance of 200 feet.
  • It is highly recommended to have reflective tape on your body, bike (crank arms, wheel rims, forks and seat stays) and helmet facing in all four directions.
  • All riders must wear a helmet.
  • All riders must display their rider number so it is visible to time-keepers, SAG drivers and rest stop volunteers.
  • Any rider who does not follow the above rules will be disqualified (DQ) from the event.
  • Any BOB double century rider who does not follow the above rules, or does not check in at each rest stop, will be disqualified (DQ) from the event, and will not receive CTC credit.

ROAD HAZARDS

Wet roads!  

In the morning, both dew and fog will make the roads wet and slippery. You must take that into account on all of the descents.

Gravel and rocks on the roads  

Be alert for this on every sharp corner. The roads on these routes are subject to frequent rockfalls.

Heavily trafficked intersections

  • Pinehurst and Skyline - Increased traffic as you transition from rural road to residential urban.
  • Grizzly Peak at Claremont/Fish Ranch Road - Be watchful of the cross-traffic.
  • Grizzly Peak at Marin - Marin Avenue is extremely steep, and cross-traffic may not stop.
  • San Ramon Valley Blvd/Foothill Road Overpass - Extremely busy where this road crosses the 580 freeway; be aware of on and off ramps.
  • Calaveras Road stop sign at the 680 freeway off ramp - Watch for fast cars; they have the right-of-way and do not stop.
  • Schaefer Ranch Road at Dublin Canyon Road - Fast cross-traffic, and you'll have to brake hard for the stop sign.

Other hazards

  • Descent of Mt. Diablo - Sharp corners, gravel, vehicle and bike traffic.
  • Diablo Road - Traffic and no bike lane (be alert although motorists are generally use to cyclists on this road).
  • Crow Canyon (westbound between San Ramon Valley Blvd and Bollinger Canyon Road) - No bike lane; be vigilant, and use the rightmost lane.
  • Calaveras Road - Do not miss the entrance to rest stop #5 at Ed Levin Park on the south side of Calaveras Road. Watch for the BOB sign; the park entrance is on your left (200 feet after a sharp left turn) halfway down what is called the Calaveras Wall. Do not miss the park because it marks the beginning of another long, steep descent that you do not want to climb should you miss the park.

RIDE TIPS

Best roads and views

  • Panoramas of the Bay and the bridges: Grizzly Peak Blvd - The views on the flat part (miles 15-20) are both better and safer than on the descent.
  • Wildcat Canyon, after you turn off Grizzly Peak Blvd. - This is a wonderful cycling road and you experience the sunrise as you ride Wildcat Canyon Road.
  • Norris Canyon - Just a very enjoyable back road.
  • Mt. Diablo - The entire time you are on the mountain!
  • Bollinger Canyon - Home to a huge flock of turkeys (50-75 birds), and a few ostriches and zebras.
  • Calaveras Road - Renowned for its test of your technical riding skills.

Momentum conservation opportunities

  • Initial northbound descent on Redwood Road, along the golf course.
  • Bottom of the first long northbound descent on Redwood Road.
  • Two places on the northbound lower Pinehurst descent, where it levels and straightens.
  • The first two miles of the Wildcat Road descent - right after Inspiration Point in Tilden Park.
  • The Norris Canyon descent.
  • Blackhawk Road - North and west along the golf course and after the saddleback bump.
  • Bottom of the last northbound Calaveras descent from false summit.
  • Vineyard, southeast from Pleasanton into Livermore, after the short steep descent (it is rare for the traffic light to be red).

On a double century you need to maximize your speed but also conserve your energy. The most important concept is to remain constantly aware that every time you slow down or come to a stop, you then must expend a lot of energy to get back up to speed. In addition, there are certain road situations that you can use to good advantage to achieve greater speed with less energy. You do this by harnessing gravity to increase your speed, then utilize the established momentum to maintain a higher than normal speed until the momentum is expended. The best situation in which to use this technique is on a steep downhill followed by a long straight stretch of just one or two percent downhill, or followed by a level road, or even a very short uphill. With a little extra effort, you can build your speed on the downhill, then, rather than coasting or slowing on the straight stretch, shift into a higher gear and pedal with moderate pressure to maintain a greater speed for a longer distance. The results realized by employing this technique vary according to your weight, strength, wind, and road surface but, in general, you can save significant effort over the entire ride by being aware of your momentum and using it whenever possible.
