Just read an email from Ironman Wisconsin saying they are going to a "improved" rolling swim start. I'm disappointed. If there ever was a venue that could support a "mass" start it is at Lake Monona. I've done that race six times with a mass start and never had a problem finding space to enjoy a nice paced swim. I don't think this change will play a big role in any decision I may make on doing the race again as the fan support makes this my #1 Ironman race and outweighs this disappointing decision by the race director.
