I just started playing with sprinting on the flats on my regular route. I say I'd average about 18mph on the flats and wanted to see how fast I can sprint on the flats without asploding. In a couple of short 20 to 30 second sprints this evening I got up to about 29.5 to 30mph. I achieved this by going down to a lower gear while on the flats, standing up and going all out for 10 seconds or so then sitting and getting into the drops to keep pedaling as fast as I can to try and maintain a max speed.

When you guys sprint, do you change gears at all or keep one gear the entire time? Should I try to get into a lower gear before the sprint, so I would accelerate slower but maybe my top speed could be a little higher?
