Okay, more hints, as requested

We rode for a total of four hours, but our breaks made it a five-hour adventure.  The last hour was in a light rain!

It was our first ride on the Silver Comet Trail, which we've been talking about, even on this blog, for a few months.  That's important because the Trail is quite flat since it used to be the path of a railroad.

So far, we have a clear winner for our game--there's only one guess!  

Careful, that's three hints.  :)
