Sounds like you had lots of fun! I could not get away from the kids (sisters) today, too bad because I live 10 miles from the start. Going for a job interview today, hope to be able to come out next time!
Oh ya, if you were climbing at 5 MPH maybe it was better that I didn't attempt right now... my 11-23 roadbike would be about 20 RPMS at maybe 4 MPH
