My youngest son and I did the Bucks County Half Marathon this morning. He is 25 and I am 54, and we each finished 9th in our age groups! I highly recommend this race. Lots of water stops. Great food after the race. Nice IT by Mid Atlantic Timing.
The start was crowded for the first mile, with a narrow path and hedgerows of brambles right up against the sides, so you were sort of stuck in the position you started. Once the pack started to thin, there was plenty of space, and tons to see in the state park. It was a small road or trail paved with asphalt most of the way.
Starting at mile 5, there was a vertical ascent of 300 feet in about 2.5 miles. Then we looped around and did the exact same climb again, this time starting at mile 10. Whew!
On the map below, I circled the climb on the elevation section of this map just so you can see when the beast will bite you if you decide to do this half.
