When I attanded a Lauren Seagrave clinic in Lake Macquarie 20 years ago there was no mention of the start. Whan asked about the start Lauren conceded to Bob Gulliver (now deceased pro running coach) that his stuff is aimed at the last 30m in a 100m race.
What I remember most was at the conference (talk in the Macquarie Shores Academy room)were Lauren said no one has been capable of teaching him how to wabble his ears and knowing all the fancy drills and being able to do something yourself will not make you a coach.
