The hashtag #CFL500K has been popping up on our Twitter timeline throughout the month of January, and we were curious: What is it? What does it stand for?

It started off with Riders fan Stephen Safinuk tweeting out a challenge.

Got @balaneski joining the 500Km of running/walking in 2019. Anyone else wanna join in the fun? #CFL500K seems like a fun hashtag. More people will help keep me honest! — Stephen S (@Safimod) January 3, 2019

Now, 500 km sounds like a lot — but spread out over 365 days, it’s a manageable average of just 1.37 km/day.

Fellow fans have jumped on the hashtag, and begun posting their own progress.

The beauty is that even though January is nearly in the rearview mirror, it’s still not too late to hop onboard; with 334 days remaining in the calendar year, you’d still only need 1.5 km/day to be on-track for the #CFL500K in 2019.

It’s a fun initiative, and obviously fans can play with the target numbers and means of getting there. 🏃‍♀️ 🏃‍♂️
