I actually did that a couple of weeks ago.....But I was not going to go home...I have the platform adapters on the other side of my SPD's so I rode on those. I was wearing my Keen sandals.....They are comfortable and sturdy. I was over compensating with my knees to make sure I didn't slip off the pedals, and was ok. Even on the few climbs we had, I really had to focus on not letting my feet slip. My knees were a little sore after 32 miles.....

I also, now have a list and double check for everything...
