Ran my first half today. 21.90 km is the google earth distance. Below is the profile:
The one pathway was closed so I had to huff it up a hill to connect with the other path. Google states a 21% grade and I believe it. That hill nearly killed me. I had to stop and and catch my breathe at the top. There were several other big hills on this run that I also slowed to a walking pace at the top. I think there was a total of 5 times that I slowed right down.
Final time was 128 minutes over the 21.9k course for a 5:50 pace. I’m pretty happy with that considering all the walking I did.
