Start Line Information

**All  information is subject to change


Runners in the 2022 Ottawa 5K presented by ASICS Runkeeper, Ottawa 10K presented by Otto’s Ottawa,  Ottawa Half Marathon presented by Desjardins and Tartan Ottawa International Marathon events will be sent off in a series of rolling wave starts organized by corral. Please read below for more information about Corrals and Wave Starts.


Each start line area will be divided into CORRALS designated by coloured flags that correspond to the coloured bars on the Tamarack Ottawa Race Weekend race bibs. The colour on your bib represents the projected finish time you selected when registering. PLEASE line up in the corral that matches the colour on your bib.

Please note: The start line can be a busy area, so please give yourself plenty of time to get to your corral.

The following provides the projected finish times and corresponding corral (by colour) for each event.

There will be Wave Starts in the 5K, 10K and Half Marathon events.

To spread the field out at the start, runners will be sent off in a series of waves starting with the blue corral, followed by orange, yellow, green, purple and red corrals.

Each wave will be sent off approximately every two minutes until everyone in that corral has started. As a wave is sent off, the next one will be brought forward to the start line and directed to wait until given the signal to start. This process will continue until all corrals have left.
