This event is hosted quasi-brevet style: Only fully supported for KOM century option. You’re on your own, but may bring private SAG on the 2nd half.

This is one of the toughest doubles! Before you sign up, please consider that to be successful at this event you should have completed one or more of the toughest doubles (Terrible Two, Devil Mountain, Heartbreak) well within their respective time limits, and be willing and able to ride self-supported for the last 90+ miles.

Held in conjunction with the Mulholland Challenge, the first 106 miles are the same; so you may qualify for the King of the Mountains Century Challenge if you wish.  The second half has less climbing, looping to the coast via Latigo Canyon and back via Camarillo and Moorpark.  You may, and we do encourage you to, have private SAG meet you at the host hotel after 106 miles; and provide leap-frog style support for the duration of the event. There are no SAG drivers on the second half of the route; so you must be willing and able to finish on your own. You may be required to show “proof” that you completed every mile of the second half, by submitting your personal Strava record. When you finish, you’ll return to the host hotel lobby and sign in with your finish time. If you don’t sign in, you won’t get credit for the ride.

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. The course will NOT be marked. We trust that as a seasoned endurance rider, you’re proficient at reading a route sheet and/or you’ve invested in a GPS based cycling computer or smart phone 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.
Please understand and take responsibility for navigation.

Route Sheets and GPS Files:
Route sheets are available in excel format to registered riders if requested via email up to 3 days before the event. We can’t guarantee that advance route sheets will be 100% accurate. Though not anticipated, last-minute routing changes may be required.

Please download a map and GPS file from RideWithGPS.com. 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.

Ride Description:
Be ready for a course that is as scenic as it is challenging. Spend the day riding the best of Southern California’s roads less traveled. Ride up, over, and along mountain peaks and ridges, and through a multitude of canyons and countrysides. Basically, this route is for the rider who loves to climb and to see a lot of diverse terrain in the process. It is one of the toughest double century events in California (#3 with respect to accumulated elevation gain). Bring gears! Some of the roads have steep sustained climbs of 12-14% with pitches up to 16%. Unless you’re a super strong climber, we suggest a triple crank, or at least a 30 cog in the back.

Your day starts with Stage #1 of the King of the Mountains Century Challenge:  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 loop back to Agoura. Bust your quads on the short but steep climb up Westlake, then enjoy the silky smooth new pavement on Yerba Buena and Cotharin, before descending to the beach via our signature descent on 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 second half is a whole lot easier than the first half (at least after you’ve climbed Westlake for the 2nd time).  Enjoy the smooth, fast descent down Encinal, then the flatlands on the coast out towards Oxnard, around Camarillo and returning through Moorpark and Hidden Valley. 92 miles with less than 6’000′ climbing will feel like a piece of cake after your quad-busting morning.

Twilight:
Twilight begins 6:00am; Twilight ends 19:51. Sunrise is 6:25: Sunset is 19:25.

Lights and Gear Drop:
Given that the last portion of the route may be ridden brevet-style there will be no gear or lights drop for this event. Of course you may leave stuff at the Hampton Inn to pick up as you come through at mile 106. If there is any chance that you’ll be out past sunset, you MUST have both a headlight and a taillight attached to your bicycle, and you MUST wear a reflective ankle band on both legs. Please do not under-estimate the time you’ll need to complete this event. Come prepared with a very good light and batteries, plus at least one non-blinking taillight and lots of reflective gear.

Personal SAG Vehicles:   Riders may have private SAG after the leave the KOM finish line.  Private SAG may provide leapfrog support onlyAbsolutely NO FOLLOWING. If your personal SAG is on the course on the KOM section, you’ll be DQ’d without a warning. The definition of 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 to any rider, or taking photographs, or simply out cheering. If you’re bringing someone with you who wants to be out on the course on the first half of the ride, please have them contact us and join our volunteer staff.

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