This is only my 2nd year of Tri's so I'm still a relative rookie. That said in my last Sprint my t1 was :48 (I have my shoes pre-clipped and do flying mounts) and my t2 was 1:42 (again leaving the bike shoes clipped in on the bike). My extra time between t1 and t2 is directly attributable to the extra stuff I take off and on. Off with the helmet, on with the run visor. Race belt clipped on. Probably the longest was tying shoelaces. I usually use Yankz or some other elastic laces (just slip on) but for whatever reason hadn't put them on these shoes yet. That probably would have save me the longest amount of time. Not sure velcro is going to be all that attractive, imo. Too many flashbacks to Zips and other kids shoes. Besides, a set of elastic laces cost maybe $3.
