Metric and 3/4 Century: 8 hours – based on the 8:30am start.
Chip-Timed Event:
This is not a race – it’s a timed event. You must hang your timing chip facing forward on your handlebars, and you must check in at the finish. If you fail to properly place your timing chip, or don’t pass under the start/finish, you’ll be listed as DNF in the results. Please don’t email us after the event to change your results if you didn’t follow these instructions.
Sticker Stops for KOM riders:
We’re no longer doing stickers. We’ve decided to trust that you are honorable and will ride every inch of the course without modification, or you will admit you didn’t and let us know you DNF. There can only be integrity in our sport if each person is honest about their efforts. We thank you in advance for your trustworthiness. That said, if there’s any disputes or accusations please plan on showing proof of completion via Strava.

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:
- 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.
- 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.
- GPS batteries on many “bicycle” GPS units may not last for a century. Make sure you’ve arranged for additional power.

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 that riders prefer course markings; however, many of the towns/cities/counties specifically forbid it and in some areas traffic makes it unsafe. Generally speaking, local residents hate it and complain about it every year.
For these reasons we will no longer be course marking at our events.
We trust that as a seasoned endurance rider, ready and willing to ride 100 to 200 miles, 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. The above routes may not be the actual event route; so please download via the event invitation only.
Our experience is that riders get lost whether the course is marked or not; and fewer riders get lost when they’re mindful of where they are on the route sheet. Please understand and take responsibility for navigation. If you are particularly navigationally challenged, please get a GPS or use your smart phone and download the route!
Personal SAG Vehicles:
Not allowed! If you bring one, you’ll be DQ’d without warning. The definition of a 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. Please understand that our permits simply don’t allow dozens of extra vehicles on the roads or at checkpoint locations. Imagine the traffic from all those cars! If you’re bringing someone with you 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.

OLD COURSE INFORMATION: PLEASE DISREGARD EVERYTHING BELOW.
We’re keeping this just in case construction or other issues require us to go back to the old route.
Ride Description:
Note – Route sheets are available in excel format to registered riders if requested via email between 2 weeks and 5 days before the event. However, we can’t guarantee that the route sheet will be 100% accurate. Though not anticipated, last-minute routing changes may be required. Links to the RideWithGPS.com maps and download files are below.
This epic route is as scenic as it is challenging. The course can be described as dramatic, epic, diverse, and beautiful. Ride up, over, and along mountain peaks and ridges, and through a multitude of canyons and country sides. Basically, this event is for the cyclist who loves to climb and to see a lot of diverse terrain in the process. Bring gears! Some of the roads have steep sustained climbs of 12-14% with pitches up to 18%. Unless you’re a super strong climber, we suggest a triple crank, or at least a 30 cog in the back.
Your day starts as you’ll head across Mulholland into the Valley and then hang a right on Topanga. After a fairly gentle climb and a super fast descent, the real climbing begins as you head up and over Old Topanga. Then you’ll tackle Stunt, zip down Piuma back to Mulholland; and take that all the way to the coast. A short ride on PCH takes you to Yerba Buena and Cotharin, before hitting Ventura County and the beach via Deer Creek. After an easy, flat cruise back south on PCH, you’ll climb up Decker Canyon hang a right on Lechusa and climb Encinal Canyon back to Mulholland. From there it’s mostly, but not all, down hill back to Agoura via Cornell. 106 amazing miles with 12,700 feet of climbing.
The 74 miler diverges from the KOM route by taking Encinal to Decker Canyon; and then gets back on the route from there to the finish.
The 58 miler diverges from the KOM route after the second SAG/Sticker Stop at Peter Strauss Ranch.
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:
- The ROUTE SHEET is gospel. Whenever the route sheet and the GPS unit disagree, the route sheet is correct.
- A GPS can (and will) route a rider over a cliff. There’s really no substitute for the human brain, so please use yours.
- Never depend solely on a GPS. Bring your route sheet, and know how to follow it.
- GPS batteries on many “bicycle” GPS units may not last for a century. Make sure you’ve arranged for additional power.
- OLD INFORMATION. DO NOT USE. SEE ROUTE ABOVE. Click here to see the 106 Mile – Full KOM Distance map on RideWithGPS.com . Click here for the 74 Mile map. Click here for the 58 Mile map. You may also download GPS files from this site.
Routing and Navigation:
Planet Ultra route sheets include lots of information to help riders navigate the course. For example, we tell you if a turn is at a stop sign (SS), traffic light (TL) or T-intersection (T-int). We know that riders prefer course markings; however, many of the towns/cities/counties specifically forbid it. Further, your Planet Ultra staff travels to the event destination the day before to make everything happen; so we can’t mark the course in advance. If we have the manpower, we’ll do our best to mark the course (unless it’s forbidden by our permits, otherwise illegal, somewhere that locals would be really upset about it, or the turn is at a place that’s very obvious, like a big green highway sign). Our experience is that riders get lost whether the course is marked or not; and fewer riders get lost when they’re mindful of where they are on the route sheet. Please understand and take responsibility for navigation. If you are particularly navigationally challenged, please get a GPS and download the route!
Parking at Hampton Inn:
If you’re not staying at the Hampton Inn, please do not park in any hotel spots. We’ve secured permission to use parking spaces in the office lot directly next door to the hotel at 30301 Agoura Rd. Please use only the spaces nearest the freeway at the back of the parking lot. Please do not park next to the buildings as some of the tenants are open for business on Saturdays. Thank you for your cooperation and courtesy with the parking situation. If we don’t abide by the request of the office space owners/tenants, we’ll not be allowed to park there next year.
