Prediction Run Series
This fun and free event put on by the organizers of the Tamarack Ottawa Race Weekend is perfect for runners of all speeds. The only requirement is that you guess your 5K time and then go run a great 5K route—without a watch!
This is how it works. After gathering on the bike path near the Cartier Square Drill Hall (beside Marion Dewar Plaza) at noon, we’ll set the clock for the slowest predicted time and begin the countdown. Runners start their 5K when their predicted time shows on the clock.
For example, when the clock shows 30:00, runners who guessed they will run 5K in 30 minutes – or 6 minutes/km – will start. Five minutes later, runners who guessed a 25:00 time will start. To help everyone manage their time over the lunch hour the targeted FINISH time will be 12:40. So with a 30 min predicted time you should start at 12:10, with a 24 min predicted time you should start at 12:16. If you pre-registered on-line you can show up at the start on the Canal only a few minutes before your start time to check in.
