The concept of this one is simple: Run 5K at your Chilly Half goal pace (or the pace you would target if you were racing it hard) and win a prize!
WHEN?
Saturday February 21st @ 9AM. This is the perfect timing to test your race pace pre- Chilly.
COURSE:
We will be using the H+P SVEC 5K route which you can check out HERE.
Our back up will be using ring road at UofW- stay tuned for details on this of needed.
TIMING:
Results will be posted on HPWR.
Timing will be completed using the SEGMENT. The start and finish point will be marked, but make sure you start before it and end after it so you register a time.
Also make sure you start a new activity on your watch, make sure your activity is public, AND make sure you have turned off hide start/end point.
PRIZING:
When you register, you will enter your GOAL PACE for the Chilly Half. They key is this has to be a LEGIT, challenging HM goal pace for you (even if you don't intend on chasing it at Chilly). We'll know if you're slacking! :P
If you hit your time, you got a Chilly Half prize pack!
(1) A H+P Winter Hat for race day.
(2) Buff from My Next KW Home Group for race day.
