TMBRA race plates:
TMBRA will use one standard plate for the series. Every race participant is required to utilize a season plate for race scoring and timing. After registering for an event you will be asked about your season plate status. If you pre-purchased your plate through the website or you picked up a plate at a previous event then select “No, I already own one.” otherwise select “Yes, assign a NEW plate.” if you do not already own one. Select “Yes, a REPLACEMENT plate is needed.” if you need a replacement for your previously assigned plate. A one-time $10 charge will be added to your event registration fee if you select a “yes” answer.




Do I have to sign a waiver?
Yes, for both DORBA and 4R. You must sign the waivers online to complete your registration.

How do we reserve a campsite? 

Pricing is per person per night in the West-Of-Creek Dispersed Campsite. There are larger group campsites with fire pits available in what 4R calls its Original Campsites.  You can purchase camping spots for yourself and for additional attendees through HipCamp. Questions about camping should be directed to Walt Roper of 4R  Ranch at


How can we find out more about each campsite before we reserve? 

Please read through this PDF for more information about the sites.


What about RV camping?

RVs are welcome, but no RV sites with hookups are available for this event. RVs will have to boondock. Generators are allowed.


What about campfires and firewood?

There is currently a burn ban in effect so campfires will not be possible. Should that change, only a limited number of fire rings are available – campers are encouraged to bring their own.  Firewood will be available for purchase.


What’s the bathroom situation?

There is a non-flushing toilet in the toilet shed (Sitzen und Schitzen). There are two sinks and two showers in the shower shed (Sudzen und Scrubzen). The water temperature for the showers is fixed. Showers are operated via pull chains.

There will also be porta-potties around the venue.


Where can I stay if I don’t want to camp?

4R has compiled a list of other accommodations in the area. Please visit their website for the full list.

Will there be water?

Potable water will be available on site but we encourage you to bring what you need.


Will there be food?

TBD, but the tasting room will be open both days and they have food.

Is there wifi or cell service?

Don’t count on either. Cell service is spotty and wifi will only be available in certain areas.


Is this event rain or shine? 

Yes, the Brambles trail is reasonably rain resistant and we will run a shortened lap that avoids the open fields if they are too soggy.
