Start Line Information

The following information is from the 2014 Tamarack Ottawa Race Weekend. It is provided here for reference. Policies and procedures may change in 2015. Please check back closer to the event date.


Runners in the HTG Sports Ottawa 5K, Lowertown Ottawa Brewery 10K, Scotiabank Half Marathon and Scotiabank 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 distinct zones or CORRALS designated by coloured flags. Each corral represents the projected finish time for runners lining up in that area. Runners should line up in the corral according to the projected finish time they submitted during the registration process.

Before the race, please head to the start line and into your designated corral. Our start line team will help guide you to the proper corral. Tip: The start line can be a busy area, so please give yourself plenty of time to get to your corral.

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

5K Under 25 min. 25-30 min. 30–35 min. 35–40 min. 40–45 min. +45 min.

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 corral will be sent off approximately every two minutes. As one corral/wave sets off, the next corral 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/waves have left.
