My previous longest ride was about 65km. I've done in the 55 to 65km range several times this month. So I decided last night to do a 100km ride this morning. I mapped out a route last night that was just a bit over 103km. I had been using 2 gels on my 60+km rides and figured 3 should be enough for the 100km. That worked out well (in my head) as I only had 3 left at home.
I started out this morning and was feeling good. About 25km or so in I missed a turn and went 8 blocks too far before I realized my mistake. I then corrected and ran into a major detour. It added probably 10km to my route but I was determined to soldier on. By about 60km in I realized that my gels were going to be inadequate.
There is a very popular dairy/ice cream shop that was close to my route on my way back (on a sunny summer weekend there can easily be 30 to 40 road bikes parked there). I decided I would adjust my route to go by there on my way back. That motivation certainly helped!
When I got there I got my ice cream cone. I don't know if one ever tasted so good! That gave me the energy I needed to make it the rest of the way home. I live up on a hill so that last hill up to my house hurt more than it has in a long time but there was no way I was stopping!
My final distance was 120.2km with 705m (2312') of climbing. Elapsed time was 4:44:30 and time on bike was 4:20:47 for an average speed of 27.7km/h. All things considered I'm pretty happy with my results. I certainly have some goals I can set for next time... Better speed, more climbing, etc.
