Times and Time Limits
Rider check-in is 6:30 to 8:30am at Campolindo (7:30 to 10:00am if you use the alternative car-free start). We urge slower riders to get an early morning start.
Hot food is available at the finish (Campolindo) from 11am until 6pm.
Overall Closing Time
Overall closing time is 6:00pm. We won't try to haul you off the course at 6pm (these are public roads, you can ride all night if you want!) but at 6pm our volunteers will be packing up to go home.
Rest Stop Opening and Closing Times
|Rest Stop||Opening Time||Closing Time|
|Island Picnic Area||7:30 am||10:30 am|
|Port Costa||8:45 am||1:00 pm|
|Briones||9:45 am||2:30 pm|
|Firehouse||11:30 am||3:30 pm|
|Proctor School||12:30 pm||5:30 pm|
SAG support on each course segment ends correspondingly.
Start early if you want to complete the entire 102 or 110 mile route . . . especially if you want food at the end! Briones and Proctor stay open late to support people who ride only the North Loop or ride home directly from Proctor. Their closing times are too late for people attempting either of the full century routes.
All full-century riders who leave the Firehouse rest stop in Redwood Park after 3:30pm must turn left and do the Proctor Out-and-Back (102 mile route), not the full South Loop (110 mile route).
Slower riders attempting a full century. It is a challenge! You need to start early and keep moving. Here are suggested timetables if you want to finish the full 110 mile route before the 6:00pm food cutoff. A rider who starts early and averages 11mph rolling speed between rest stops (which is midpoint of GPC's T pace) can afford just 15 minutes at check-in and rest stops, and no other stops, as shown in the table. That's not much! A rider who averages 12mph rolling speed will finish with a greater comfort margin. A better choice, if you're running slow, is the 102 mile route. Make your choice at Firehouse Rest Stop. It is still a full century!

The table is not fully realistic. It optimistically assumes the same rolling speed for the afternoon loop, but in fact it is hillier plus you will be tired by then.
