With this first attempt, I would like to encourage people to run this challenge unsupported. I did not have time for a longer run, but I will do the real full day challenge next time when I am in NYC. This time I wanted to run the full central park loop and this lower loop. Unfortunately, I could not do more than one lower loop as I had to go back to work.
Weather: sunny, about 5 degrees Celsius at the start
Trail: thousands of runners, walker and tourist on the track as it was a lovely Sunday morning.
Fun factor: running on this loop is just fun: amazing atmosphere and great running sprit. For me this is the real central running place on earth.
Editor: 1 loop achieved unsupported.
