14 mph? 1st group ride I did in my town was with an older group- They were on Road bikes- and I was on the MTB with knobblies. Only a 40 miler and took in about 5 mile of flat before the first hill. Off they went and it was 12mph. That was too slow even with my handicap of knobblies and heavy bike. Came to the first slope and the speed did not change- Long climb to the top of the hill and gravity took over on a 10%. Speed- 12mph. Then came a hill- 1 1/2 miles at 12% and the speed- 12mph. I was puffing at the top of that one- I must admit. Then down for Coffee and they found a superb cafe- but this lot were Tea Drinkers. No stimulants for this lot. Off we went again and we had done about 20 miles and I called it a day. That ride was the most boring I have ever been on in my life. As I left them I was at the bottom of one of my offroad climbs- But I have to admit that I slowed to less than 12mph on that one- More than made up for it on the downhill though.

Good luck on the ride and pics are required.
