I can pretty much guarantee that if the words "Andrew" and "saddle" are ever spoken near anyone in my training group, they will cringe on the spot. As I began seriously training for triathlons, so did a saddle saga that lasted a solid couple of months. Anyone who has dealt with saddle issues knows how difficult a situation it can be. Instead of focusing on your form, pace, hydration/nutrition, or other aspects of the ride, all you can think about is what is between your legs (get your head out the gutter).
As I mentioned in a previous post about my bike I had switched from my stock saddle to a Nashbar F1 road saddle. It was a good fit for me for traditional road riding, with just the right amount of cushion and an ergonomic design. It supported me well on rides of any distance and gave me several good years of service. After installing aero bars onto my bike, it quickly became clear that this saddle wasn't going to cut it for me.
