Lluvia, I am also doing an MS Ride in October. I am doing the whole 150 (over 2 days), and I'm very nervous about doing 2 days in a row.

My first long ride was just a few weeks ago. My husband and I rode the Tuscaloosa Hot Hundred. We had intended to go only the 46 mile route, but met up with a single rider and ended up riding with her for the 65 mile route. It was the farthest I had ever gone!

Before that ride, I had only done 30, like you. Also, I ride on flats and the Tuscaloosa ride was hilly, so it was extra challenging. I did just fine - and I must say I was surprised. I attribute a lot of it to proper nutrition and hydration, so make sure you study up on that before your ride.

Good luck!
