Gauging the 10m rule for Drafting
I was wondering if anyone had any good techniques for gauging the gap to a rider in front?
I know the draft zone distance has increased from 7 to 10 metres (and the subsequent time allowed to carry out an overtake) but the last thing I want is to get a penalty for being in 'the zone' too long, especially as I'm doing some hilly triathlons where I might not be able to muster the required speed difference to make the overtake in the time allowed - I seem to catch people very slowly.... if at all especially on hilly or windy courses
Should I use an adaption of the 2 second rule you use when driving? where you see the person in front pas a stationary object and you count "one ellephant, two elephant" or resight "Only a fool would break the two second rule" to yourself and jusdge whether you have reach that same stationary point?
or is there another method?
