Start / Finish Location:
TBD. We will NOT be at the Sheraton for 2017 and beyond.

How to Get There:  
From the 101 Freeway north or south: Click here for a map.


Check In:
Friday night from 7:30pm to 9pm at location TBD. Saturday morning from 6am to 7:15am.

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.

Start Times:
106 Mile-Full KOM Riders may start between 7 and 8am.  Here are some guidelines based on your expected finishing time:
9-10 hours: 7:00am
8-9 hours: 7:00-7:30am
under 8 hours: 8am

73 Mile Riders may start between 7 and 8am.
52 Mile Riders will start together at 8:30am.

If you leave before 7am, you won’t get a start time, as our timing equipment won’t be turned on until 7am. In addition, you may reach a checkpoint before it opens – and you’ll have to sit there and wait for the mandatory sticker. Under no circumstances will stickers be distributed before the checkpoint opening time posted on the route sheet. Please folks, let the riders who need the time get a little head start.

Time Limit:
106 Miles – Full KOM Distance: 11 hours – based on the earliest start at 7am. All riders must be off the course by 6pm. No exceptions.
70 Miles: 8 hours.

Sticker Stops:
There are several locations on the course, indicated on the route sheet, where riders will receive a KOM Polka Dot sticker as proof of both completing that section of the course within the time limit and their ability to follow the rules of the event. Stickers are placed on the rider’s number, which must be on the rider’s back, and visible, at all times. At the finish, riders must show their number to prove they finished the entire course. Any rider who fails to receive all stickers required for their distance will be DQ’d. No exceptions.
106 Mile sticker stops will be located on Old Topanga, top of Stunt, Yerba Buena, Deer Creek and Decker.
73 Mile sticker stops will be located on Old Topanga, top of Stunt and Decker aid station
52 Mile riders do not require stickers.

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!

Personal SAG Vehicles:
Not allowed! If you bring one, you’ll be disqualified from the event 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 the 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.

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 73 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 52 miler takes Stunt as the first main climb, then joins the 73 mile route to Decker and then descends back to Agoura via Westlake and back to the finish.

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. The ROUTE SHEET is gospel. Whenever the route sheet and the GPS unit disagree, the route sheet is correct.
  2. A GPS can (and will) route a rider over a cliff. There’s really no substitute for the human brain, so please use yours.
  3. Never depend solely on a GPS. Bring your route sheet, and know how to follow it.
  4. GPS batteries on many “bicycle” GPS units may not last for a century. Make sure you’ve arranged for additional power.

We always need volunteers! Click here for info about available positions. To provide a little incentive, when you help at a Planet Ultra event, you get a voucher for a future event entry for only $25. Please contact us to let us know when and where you’d like to help. We also appreciate when riders recruit family and friends to help. If you recruit someone that wouldn’t use the coupon, you’re welcome to use it yourself. Ride credits must be used within a year of the date of volunteering and must be redeemed using the mail-in entry form during the early registration period.
