PenVelo meets about 20 minutes south of SF on Canada road
Saturday - 8:15am
"re-group" ride This ride regroups at the Woodside Bakery after the warmup along Canada Road. After riding counter-clockwise around the Portola Valley loop, there's a final regroup at the Chevron station on Woodside Road, immediately after turning off Whiskey Hill Road.
Sunday - 8:00am
"no-wait" ride - very fast pace Same route as the Saturday ride WITHOUT any regroups.
Tuesday and Thursday - 6:00pm
"no-wait" ride - VERY fast pace These rides occur April through October, when daylight savings time is in effect. Note, this time span largely coincides with the Racing Season. These rides are very fast paced with a great deal of aggressive riding.
On Tuesday night, the ride turns east off Canada Road onto Woodside Road and continues around the Portola Valley loop in a clockwise direction. These rides differ from the weekend rides as they're routed directly along Alpine Road instead of along Foothill, Page Mill and Arastradero Road. On Thursday, the route is the same as the Tuesday ride except in the counter-clockwise direction, by turning west onto Woodside Road.
