About this event

Son of Sno*Drift XXV

Winter TSD Tour Rally

Saturday, January 14, 2023

  • Straightforward Time-Speed-Distance (TSD) Tour Rally – no traps
  • ~175 miles of mostly unpaved roads in Washtenaw, Jackson, and Livingston counties
  • All passage controls using Richta GPS app
  • Novices (< 6 combined rallies between team members) welcome and encouraged
  • Points toward Detroit Region, Great Lakes Division SCCA Divisional and the SCCA National Road Rally Championships
  • Winter tires, nighttime driving lights, snow extraction equipment recommended!

NOTE: We will be using the Richta GPS Checkpoint app. 
Look for "Competitor Richta GPS Checkpoints" app on Google Play Store or Apple App Store or click on the appropriate link:
Prior to the rally, all the checkpoint information (locations by Latitude and Longitude and the correct arrival times) is loaded onto the internet by the rally master. People who register for the rally are given a car number and the password for the app. Each Rally Team then goes to the site and downloads the information for their car.  The contestants will NOT be able to view Rally Master information. During the rally, when each car reaches a checkpoint, the contestant’s device will signal a checkpoint has been reached with a “bing-bong” sound. The device will then display your time entered and your score and say “early” or “late”. Your total score for the rally to that point will also be displayed.

Visit the Richta app information page at to learn more about how the app works and how to use it.

With very few exceptions, this rally will run to the SCCA tour rally rules. 

Start/ Finish:  Aubree’s Pizzeria & Grill, 21775 Pontiac Trail, South Lyon, MI, 48178

Accommodations available at the Days Inn of Whitmore Lake, 9897 Main Street, Whitmore Lake MI 48189, 734-550-0105.

Event requirements

ATTENTION! If you intend to use a TSD rally app on your smart phone or tablet device in this rally, you MUST read the following carefully and register to compete in the appropriate equipment class – either Stock or Limited.

Stock class requires that you use an app that does not incorporate automatic mileage measurement from any distance measuring source. This includes any app that automatically accumulates mileage utilizing the device’s internal GPS. You must manually enter mileages into the app using the app’s mileage input function. Furthermore the mileages entered into the app must come from the car’s stock odometer. You may not use any external odometer or a GPS-based odometer app on a phone or tablet device for rally computer app mileage input sources in Stock class.

You may choose to use a TSD rally computer app on your phone or tablet that automatically accumulates mileage based upon input from the device’s internal GPS, or from a separate third-party GPS receiver. However, using an app that automatically accumulates distance based upon GPS position data places you into Limited class. YOU CAN NOT RUN IN STOCK CLASS with any app that automatically accumulates mileage from any source.

Note that Novice class requirements are identical to Stock class. If you otherwise would qualify as a Novice class competitor (driver and navigator, combined, have competed in six or fewer rallies), but choose to use an app that automatically accumulates mileage from a GPS source you must compete in Limited class.


Please read carefully:

If you are registering yourself for the first time, and you will be paying for the event entry, please choose Option 1 on the order form and follow the prompts.

If you are registering as a co-entrant and your partner has already registered, please choose Option 2 on the order form.

If you do not already have a account, click the 'Create New Account' button below. You will be asked to input your member number and Region of Record.  This is your SCCA Membership number and home region. You must have this information in your user profile to avoid needing a weekend membership for this event. (Also, make sure your user name matches exactly as it appears on your SCCA Membership card... otherwise, the member verification process will not validate your membership.)


Son of Sno*Drift is NOT to be confused with the “Sno*Drift” Performance Rally, which is part of the American Rally Association series.  Son of Sno*Drift is expected to be a challenge to the driver, navigator and vehicle.  Suitable tires and nighttime driving lights are recommended.  Snow extraction equipment is also a wise idea.  This should include, warning triangle(s), tow strap, shovel, etc.
