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||5:00 pm|
SAG support on each course segment ends correspondingly.
Start early if you want to complete the entire 102 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 the full century route.
52 Milers, Don't Start Too Early
For our 52 mile route, please do not leave too early. The route is designed for people who ride 12 mph average or less and want to enjoy the scenery. If you start too early, like before 7 AM, or hammer the route, you will arrive at our Briones rest stop before its opening 9:45 AM, and possibly at lunch before its opening at 11 AM. This route is truly very scenic and should be enjoyed! Slow down, be safe, and enjoy the ride!
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 century 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.|
