I've decided to try to ride my first 100K next Saturday. Saturday I rode with a group of folks who ride at a very casual pace. We rode a total of 47 miles and it took about 5 hours. We stopped at things interesting to look at and took a long break near the half way point. At the time I didn't think I could go much futher. I'm not sure I can go 62 miles.
My question is...can riding slowly actually make it harder to go 100k? I'm wondering if I should go at a slow pace or try to sustain a brisk pace? I'm afraid that riding slowly will only equal more time on the saddle meaning a sore butt, sore arms and a sore neck (my neck was really bothering me on the 47 mile ride). I know that going too fast might burn me out but can riding too slowly do the same thing?
