I'm no expert, but from what I've read here, gel saddles are best for short rides as the gel will deform and put pressure on areas you don't want pressure on. I'm experiencing that with my current Serfas gel saddle on rides over 15 miles. I'm looking at something like a Brooks or the Selle an-atomica for longer rides. Apparently, harder saddles are best for longer rides.
Good luck
