THE DREAM
This is the 4th edition of the race.
It's an elimination-format race in which runners repeat a 5k loop at set time intervals.
Picture the course in advance
and find the pace that fits you.
Streets lined with cheers, runners all around.
You'll be part of that scene.
Take it slow with the finish still in you,
and meet the city all over again.
From the joy of finishing to the tough moments — read what runners wrote themselves.
“WE DID IT! Neither of us walked a single run.”At the 2024 Waterloo Death by 5km, the runner and their husband completed ten 5km runs over 24 hours. They ran every leg without walking despite daytime heat and a lack of sleep overnight, and appreciated the hot meals and friendly organizers.
We translated a short line from each public race report and summarized the experience. Finish times are as stated by the author, and past editions may differ from this year's weather and operations.
