In a 400m race on a track with semicircular ends of radius 35m, the inner lane (Lane 1) has a total length of exactly 400m along its inner edge. Lane 2 is 1.2m wide and is immediately outside Lane 1. How far ahead of the Lane 1 start line must the Lane 2 runner start to run the same distance, assuming they run 20cm from the inner edge of their respective lanes?
