PARKING & COURSE UPDATE !!!
FIRST - I Goofed and didn't include the link to your Dashboard Park Pass. Sorry!!!
PRINT OR DOWNLOAD PASS TO YOUR PHONE HERE
You will need to show this pass at the entry station as you go into the park. I was wrapped up with the last minute course re-design.
PARKING UPDATE: The snow total in the park was less than an inch, and it won't be snowing again until 2pm on race day! We will be able to park all runners in the close-in lots, and no shuttles will be required. Your walk from your car to the start line is about 2-3 minutes.
START TIME: The 5K and the 10K will be starting together at 10:00am. Please, do not miss the start. The follow vehicle will leave immediately after everyone crosses the start line. You must start before the follow vehicle.
COURSE CONDITIONS: Even with the minimal snow, the park rangers hit the course with their snow plows. When I left this afternoon, the road was almost completely dry, and the paved bike path section (10K only) has just some small patches of snow which is easy to avoid.
FORECAST: for the race start is 20 degrees and cloudy, with a light breeze.
We'll see you on Sunday morning!
