Short answer: junior parkrun events are 2 kilometers in distance. Context and details to help you plan:

• What it is: Junior parkrun is a free, weekly timed event designed for children aged 4 to 14. The course distance is fixed at 2 kilometers, unlike the 5-kilometer adult parkruns. It’s held on Sunday mornings in many locations, typically around public parks or open spaces.

• Age and supervision: Children aged 4 and up can participate, and those under 11 must be accompanied by a responsible adult who remains with them for the duration of the event. Parents/guardians are welcome to participate or volunteer but are not eligible for a placed finish.

• How participation works: Participants usually register online to print a personal barcode, which is used to record their time and distance at any junior parkrun worldwide. Milestones (e.g., 11, 21, 50 runs) earn wristbands or certificates, and junior runners can receive a white T-shirt after 10 runs, with additional milestone shirts for higher totals.

• Locations: There are multiple junior parkruns, including in Ireland, the UK, and Australia, with each event offering a safe, marshalled course where juniors are within sight of at least one marshal at all times. Check the parkrun website for your local event map and details.

• Not a race: The emphasis is on participation, fitness, and fun rather than competition; walkers and runners of all speeds are welcome, and there’s no requirement to complete the course in a particular time.
