I was in a 35 mile breakaway in a 55 mile RR this weekend which had a 2 min gap on the peloton at 10 miles to go. It was hard to calculate what distance/gap was required before we could ease up our pace. Does anyone have a simple calculator for "what if" scenario building? (i.e. 5 mi remaining - 1 min gap - peloton needs to ride + 2mph...or whatever it is...). Please post any spreadsheets or online calculators...I know the Pro Teams have all that stuff on computers, so it must exist somewhere on the internet.
