F50, solo or not?

I've done the Firecracker 50 many times. It is a staple for the 4th of July holiday. But no matter the fitness I may or may not have, it is so freakin' hard. 4.5hrs, give or take. Where is the reward, one might ask? Not really sure anymore. I am probably going to grind out the 50mi solo, but I may do a team race and catch, for the first time in many years, the town parade. Alina would love it, that alone is reward. hmmm...
