If you swam the mile tapered, I am sure that you would drop alot of time. Last year at IU Invite i was 20+ also, then taper and drop 2 minutes. This thursday we leave for the IU Invite again, hopefully all goes well. My lineup is 50, 100, 200, 500, 1650 free plus any B relays that I might be on, if any. I remember the first time I broke 6 minutes in the 500, now I've vowed not to stop swimming until I break 5.....even if it takes til im 30
And your breastroke kills me, swim a 50 of it twice a year at our intersquad meet. Think i go like 37 or something like that
