Bucket List Guy

So, I'm 53 & got roped into a Sprint Tri as part of a 15-task bucket list bet. 4 mos into bet, got 5k pace from 10 to 8 min miles, bought a bike (last rode a "10 speed" in 1985) & do lo 20mph avg for 10-15 mls on flats but cant/never will learn to swim (first time on site was last nite & got good advise--lessons).  Knowing a few extreme IMs & nothing else about tri's, this is a bit cultish but I'm an early disciple.
