My DH fell on his MTB and was forced to take a week off because of his bruised ribs. He went out with me on the road bike yesterday on a short (12 mile) flat (mostly) spin. He immediately dropped me, I had my Garmin, he didn't, I was watching and I was cruising along at 24 mph on the flat....dropped. I caught up to him and said something about I guess his ribs werent bothering him. He shook his head and said his ribs felt fine but the rest of him felt terrible, his legs, his back, energy, all that. The light changed and off we went, again I was dropped, this time on a small climb (I was still doing 17 mph at the top of the climb). When I caught up to him at the next light, I figured he was feeling better. He was still grousing about how he felt. Finally, after doing the lather, rinse, repeat several times, I finally got grumpy and said, "Well, if it makes you feel better, you have dropped me four times and I am having a good day!"
