Your athlete or parkrun ID is the number underneath your barcode, beginning with A.
This is unique to you and if you don't have a barcode handy you can find it using the athlete search function.
All Athlete ID's (barcode numbers) start with an 'A', the box is pre-filled with the 'A'. Simply type your number after the A.
You can find your barcode number under your printed barcode
Or in the URL on your results page (click on your name on the event results), for example http://www.parkrun.ca/results/athleteresultshistory/?athleteNumber=2691427
Finally the athlete search function is on the results page of an event website. So pick any event, click Results, and select Search at the bottom of the menu.
If there is more than one person with the same name you may need to click through to their results to check you have the right person.
If you cannot find your barcode number, or do not know it, please use the reset link to get an email containing your barcode number. You do not need to use the reset link if you know your password.
