I ride alone. I bought an InReach so I could communicate my situation in case I get into trouble. It is a life saver but it doesn't make up for not having a partner. I was out on a trail I have ridden frequently. However this time it was after a rain the previous night. I had to climb up a fairly steep wash. The rain had made the sand soft and created some big ruts. As I climbed up I hit an off camber portion to avoid the ruts and my rear tire slid down into one. Once I was in the rut I lost momentum and had to stop. When I tried to drive out the rear wheel dug in up to the axle. I fought to get the bike out but each time I got it out of the rut and tried to get going it dug in again due to the softened sand. It was a hot muggy day so it didn't take long for me to get fatigued from trying to get the bike out of the hole. I started to feel light headed and decided I needed to get help. As I hiked up to the top I felt totally exhausted. Once I got to the top I walked out to the nearby road and sat on a rock, waiting for help. There was no shade so I sat there in the sun. I knew I was experiencing heat stroke. After about 1/2 hour I got help. 2 guys pushed while I powered the bike. We got it out easily. If I were not near a road I would likely have had to call for rescue. This made me realize that having a satellite beacon does not replace having a partner. If I had a partner I would not have had an issue. In this case I could have turned around and got out, but I could have been in a situation where I could not easily go back.
