Good that you learend how to do it. Now, work on getting faster. An hour is a long time. If I need to I can usually fix a flat (with a new tube and C02) in about 2 minutes.
On more than one occassion, on a pretty fast group ride, we've flatted, and still chased back on. Obviously, when the group is moving away from you in the mid 20's every second counts.
