The Grid - Global Time Attack Challenge

Hello fellow racers! The Perth crew have come up with another standardised track that’s super simple to set-up. Looking forward to seeing you give it a crack…

THE GRID

Global Time Attack Challenge

Inspired by the Global T-Race Challenge

This challenge is directly inspired by the Global T-Race Challenge, created to provide a consistent, accessible format for time-based PEV racing around the world. The Grid follows the same core methodology—using standardized marker layouts and GPS timing—but offers a larger, alternate layout with a bit more flow. It’s not intended as an improvement, but simply a different take on the same spirit of global competition.

Track Setup

  • 9 markers, placed in a 3x3 square grid.
  • Each marker is spaced 20 metres apart in both directions (forming an evenly spaced grid).
  • The track follows a predefined path weaving through the grid in a flowing layout (see reference image).

Challenge Format

  • Riders must complete timed laps in both directions:
    • Clockwise
    • Anticlockwise
  • Flying starts are permitted.
  • The goal is to set your fastest single lap in each direction.

Timing Rules

  • Only GPS-based or infrared lap monitor timing systems are allowed.
    • Recommended GPS devices: Dragy, RaceBox, LapTimer apps, etc.
  • No manual timing or stopwatches permitted.

Submission Guidelines

General Rules

  1. Grid spacing must be exact – 20m between each marker, forming a true square grid.
  2. The track layout must follow the official path (see provided image).
  3. No cones or markers may be skipped or cut.
  4. Riders may take multiple attempts, but must submit only their best verified lap in each direction.
  5. All PEVs welcome – eSkate, EUC, eScooter, etc.
  6. Safety gear is mandatory – helmets at minimum.
  7. Hosts and riders are responsible for accurate grid setup and fair play.

Rankings will be posted on

Looks rad. I’ll set it up at one of the upcoming I2S Utah events so we can get some times on the board. Thanks for taking the initiative!

Is this the correct orientation for clockwise and counter clockwise?

I wish this was a thing before I moved to texas because there was a parking lot that while not perfect I could have easily used for this

Maybe once my main board is up and running again I might head out to one of many empty cooperate parking lots to try this out. Mostly for fun since google maps tracking doesn’t’ take enough data points to be accurate enough to submit a time. Plus I know I won’t be high enough up anyway so if I do it I am doing it for fun and not to compete.

I wonder if my Garmin Edged 130 plus is good enough for this or would I need to get a race box thingie?

We just ran the same track in the reverse direction, like this

I might need to re do my graphic to make that a little more clear :thinking:

I would say that that favors one side over the other instead of like t-race. Not a huge deal but something to keep in mind. The two pics I sent above I think would be the best to keep both tracks the exact same.

I would have thought running the same track in both directions would equalise the left/right turns

Eg clockwise= 5 right hand turns, counter clockwise=5 left hand turns

I understand the orientation is different, but the elements are still the same, including the sweeper, hairpin and “chicane”

I do take your point though. By completely mirroring the track you get a true equalization

Don’t get me wrong, I think it will be close but if you want the true t-race equivalent. It should be the exact same both directions. Figured I’d chime in before a lot of people start doing it so we’re all the same. You wouldn’t have to change the cones at all either.

You are totally right, in regards to replicating that universal approach to track direction/orientation.

I just had a chat with our local crew - some had actually been thinking about this mirrored track approach today, coincidentally.

Ultimately we came to the conclusion that for the sake of simplicity and flow, we will keep the 1 route and run in it both directions.

This will also open up the doors for multiple leaderboards with different variations in the future, eg:

I think youre right in that It might preference one side for some, using only a single route. We found that time differences were within 0.5 - 1 second max, which aligns with some peoples t-race times.

I guess in some ways this challenge might lean more towards real world track racing, where you would usually only have the 1 route, rather than being a universally equal sided track challenge

@Yeahthatperson consider adding this to Shredmond at the end, run it at the Marymoor lot next to the velodrome :slight_smile:

I’d totally come watch, drink a beer and run it a few times.

Wait.

I’d totally come run it a few times, drink a beer and watch,

I’ll be happy to take submissions on the forum also, just might be slower to update the leaderboard🤙

ok… so we’ve had more feedback from the global and local community and we’re making changes. Appreciate you bringing this up @Swol_Moon

Thanks to our awesome riders for the constructive feedback!

To make The Grid even more balanced and fair, we’ve made one key change:

  • Clockwise runs will be on the original layout
  • Counter-clockwise runs will now be on a mirrored version of the layout


This ensures both heelside and toeside turns are tested evenly, giving everyone a true all-rounder challenge.

You can submit your fastest laps (with GPS results) to:

:page_facing_up: Full rules and format available here: esra.org.au/gridrace

Let’s see those times roll in — and remember, accuracy and flow are just as important as speed!

First entry with a combined time. I think under 20 will be possible.

It was definitely the right call to mirror the track. Glad we went ahead with it.

Hope to see some more groups around the world try it soon!
