    Results for the Rough Rider 100 are up on the West Hare Scrambles site


    Slight updates to the dates for rounds 6 and 8 on the schedule. Check it out!


    Please note: AMRA is NOT handling registration for the Rough Rider 100 in Prescott Valley. It is being handled by West Hare Scrambles. If you're trying to register for the Rough Rider 100 be sure to use the West Hare Scramble registration page.


    Merging the scores from the two races became unmanageable and has been outsourced to the author of Mototally. It will take a few weeks. We sincerely apologize for the delay. It has been a humbling learning experience significantly complicated by the requirement to score as two separate events for the ISDE but wanting a single score for AMRA. We will know better how to handle this going forward.


    The flyer for the Rough Rider 100 in Prescott Valley! has been updated. Please be sure to have a look.

    NOTE, The following corrections were made to the flyer

    • Race 4 on Saturday is the Women A, and All C Class. The entry fee is $65.
    • Race 5 is the Team Race and the entry is $40 for both riders, $20 each.
    • Mike Johns' phone number was corrected.

    Pre-entry opened on 1/17 at 2AM CST on the West Hare Scramble Mototally page


    First we'd like to apoligize for the delays and confusion. The score merging process has been more complicated and labor intensive than we anticipated. We thank you for your patience.

    Below are the results that were sent to the AMA. We are going to trophy off these results and have them at the next race. We are going to move the AMRA members from the LOI classes into their respective classes, import that to Mototally, and award series points based on those results. It’s not going to be an easy task so it will be some time before everything is up on the site. This will mean some people will slide down another spot if there was an LOI rider from their AMRA class.

    Please direct questions or concerns to the big bike steward, mini steward, or AMRA president as appropriate.

    Note that yellow rows indicate trophies will be awarded.

    Here is a version with the LOI riders put into their respective AMRA classes and divisions.
