If you can afford it for 3 months, I think that it is worth it. Especially since you will be using these lessons for the rest of your biking life....maybe all you need is only 3 mo of coaching as a recreational cyclist rather than a competitive cyclist?
Heck, I just signed up for a 2 hr mountain biking class to work on my downhill flow and switchbacks....$125 for only 2 hours of NON-Private 4-6 person class. This is not something that I will be paying for regularly due to cost, but I am excited to try it though.
