Mammoth Cave is the largest cave system in the world with over 400 miles (yes, miles!) of documented pathways. I could have easily run a marathon in the cave but alas, they didn’t let me. Instead, I had a fabulous day running a spiderweb-like figure eight route on the soft, rolling grounds above the cave.

My friend and rockstar runner Sharon joined me for the full marathon. We had a sunny 55 degree Kentucky spring day but the forecast was for three inches of snow only two days later. Talk about good timing. While you go to Mammoth Cave for the cave make sure you get the full experience by going for a hike or run on the trails and marveling that under your feet are caves that go on for miles and miles.
