I used RaceJoy for the 50 miler (Burning River) and was quite pleased with it (I also used it for Bigfoot 50k last fall and was pleased with it). At first I wasn’t sure it started because my phone said no connection. But it did pick up when I gained service and had recorded from the start line. I loved that I had it available after my running watch battery died at mile 44. The mileage, pace and estimated finish times were very helpful. I also really enjoyed the cheers that people sent me, the Star Wars themed cheers were particularly amusing. I also liked that I could look and see who sent the cheers when I was finished and could view the overall race stats. My husband enjoyed the updates he received on my progress and had fun sending cheers.
Great app. Easy to use. I recommend it to others.
