90% of my cycling is solo rides as I'm never organised enough to fit in with group rides, plus I enjoy my own company and the freedom to change the route or smell the roses. I have a bunch of friends that I do ride with occasionally but that is mostly on local rides or trips to trail centres.
I find myself preferring ad-hoc rides, depending on the weather forecast the previous night, on more distant locations up in the Brecon Beacons or along the West Wales coast where the traffic is light and there's a mix of road and light XC. Not necessarily long rides, just 30 - 40 miles, and I'm hoping for a couple of 50 miles, but it does mean packing the bike in the car and a couple of hours drive.
I sometimes worry though about the potential problems e.g. injury or bike damage - I have had some falls that caused serious knee and shoulder injuries, but luckily I was with friends.
Some of the areas I ride have no mobile phone coverage. It's not going to stop me, not yet anyway, but I am more aware as I've got older, I'm now 67, of the risks involved and my own fallibility.
I know that the definition of remote is subjective, but what do other older riders do about solo rides, especially in the parts of the US where you can be out in really remote areas? How much stuff do you carry?
