REGISTRATION OPENS NEW YEAR’S EVE!
Please read
the rules and our cancellation policy before registering.

Use the SignUp bottom to register online and pay by credit card (which includes a small service fee). 

Please note: If your 2024 goals include our King of the Mountains Century Challenge, the registration site has an option to sign up for all 3 events at once, with a discount of $44. That said, the cancellation insurance is not offered with the bundle.

Start / Finish Location: We will very likely start at Sylvan Park in Redlands (permit pending). We’re trying to keep the event consistent with its history (even though we cannot use Jackrabbit Trail). Course support and festivities will end on Onyx Summit. Thereafter you may ride down at your leisure.

Parking:  Again, very likely we will stage from Sylvan Park in Redlands

Check In:  
Friday night from 7pm to 8:30pm at LOCATION TBD. Saturday morning from 6am to 7:45am.

START TIMES:
TBD

If you’re a super fast rider and leave before your suggested starting time, you may reach a checkpoint before it opens – and you’ll have to wait, or ride self-supported.

Time Limit:
9 hours – based on the earliest start at 7am. All riders must reach the summit by 4pm.

Ride Description:
Though not anticipated, last-minute routing changes may be required. Links to the RideWithGPS.com maps and download files are below; but are subject to change.

This event is for the cyclist who loves to climb. Bring gears! Some of the roads have steep sustained climbs of 9-10%.

Route Sheets and GPS Files:
Please note that advance route sheets and gps files are provided as a courtesy and you use them at your own risk. Planet Ultra doesn’t guarantee accuracy. Please further note the following very important caveats:

  1. A few days before the event, Planet Ultra will email an invitation to the RWGPS “event” with all routes. The links in the invitation allow you to use subscription-based functions even if you only have a free account.
  2. Never depend solely on a bike mounted GPS. Bring your route sheet, and know how to follow it. Use the RWGPS app on your smart phone as backup.
  3. GPS batteries on many “bicycle” GPS units may not last for a century. Make sure you’ve arranged for additional power.
  4. ROUTE LINK COMING SOON

Routing and Navigation:
Planet Ultra route sheets include lots of information to help riders navigate the course: Stop sign (SS), traffic light (TL) or T-intersection (T-int). We know riders prefer course markings; however, many of the towns/cities/counties specifically forbid it and in some areas traffic makes it unsafe.
For these reasons we no longer mark courses at our events. 
We trust that as a seasoned endurance rider, ready and willing to ride 100+, you’re proficient at reading a route sheet and/or you’ve invested in a GPS based cycling computer into which you can upload the route (and we strongly advise that you use one). Your entry fee includes access to RideWithGPS downloads for your Garmin (or other GPS devise) or your smart phone.

Personal SAG Vehicles:
Not allowed between start and Onyx Summit! If you bring one, you’ll be DQ from the event without warning. Personal SAG is any vehicle (motor or otherwise), anywhere on the route, operated by someone other than Planet Ultra staff, that is providing any type of aid, assistance, or motivation, or taking photographs, or simply out cheering. Our permits don’t allow dozens of extra vehicles on the roads or at the checkpoint locations. Imagine the traffic! If you’re bringing someone who wants to be out on the course, please have them contact us and join our volunteer staff.

Volunteers:
We always need volunteers! Click here for info about available positions.
