It looked like you did pretty well to me considering it was your 4th time on the bike and for a person having an injured ankle. Awesome that you came out!
Build up to the clipless... Allaire is a great place to practice clipping in and out on the flat sections. You'll get the hang of it before you know it and then you'll never go back to regular pedals again!!
It was nice meet you and to see you out there tonight 🙂
