Sounds like fun the reverse chasing start. Good for a lie in and then good to chase all the way to keep you going. The Saunders used to have a mass start on day 2 which was always fun and I thin the LAMM did it early years. The Swiss MM had a mass start on day one then a chasing start so head to head all the way.
She sounds like a machine!
