There are two things that scare me on a bike. Of course, these are very relative and may be above or below someone else's "threshold". But for me, although they are attainable, they scare me, make me feel weak and intimidated and generally cause all kinds of anxiety:
1. 100 miles solo on the road bike or even 80 miles at a really stiff pace seems to do the trick (5+ hours)
2. 50 miles or more solo on a mtb nightride (5+ hours).
I find I have to think about doing either of these for some time before I launch the effort. Sure, it seems like I just wake up and decide to go for a 5 hr night ride...but it is really just the timing that has all come in to place where motivation meets weather meets schedule meets fitness.
The whole idea plays with my mind...knowing that I may reach points of suffering or might even get lost and need to spend the night. There is no finish line, no feed zone, no comfort of an encouraging word. There are no race fees and no one is cheering or even cares. You flirt with bonking and pacing and nutrition become quite important as there is no support vehicle to pick you up. There's wind, hills and spooky animals at night. If it sounds easy, or if you do either regularly, hats off to you.
I have been close to making the call of shame on road rides, dehydrated and spent on the side of the road. I have fought turning back on epic night rides when faced knee deep creek crossings or 2,000' climbs. The mental games can be intense and overpowering.
It is the risk of being vulnerable that gives me such a high. Try it, you might like it. You'll be guaranteed to learn something about yourself.
