Today I rode in my first group ride. We started out with about 10 of us, and after about 5 miles or so about 5 riders took off...They were doing an 80 mile...Not me....lol.....I was in the slower group and we rode right at 40 mile with an avg speed of 18 mph....By far my longest and fastest ride ever.....I also added about 3 miles round trip from my house to the meeting/starting point.....I finished the day with 43 miles at 17.7 avg mph........This was a good jump from my record 24 mile long ride and my normal 15-16 mpg avg speed rides....I noticed you seems to push yourself a lil harder when riding in a group. The guys were really cool and made sure not to drop me....I will ride with them again next sat for some more punishment...lol....
