Just the right kind of insane, apparently. It was awesome! And I am hooked! There were times during training when I thought that there was no way I was going to be able to finish even the measly Sprint Triathlon (440 yard Swim, 10 mile bike, 3.1 mile run). For example: my first time in a pool when I couldn't swim more than 100 yds at a time. Fortunately, I picked that up pretty quickly and I now consider it my strongest leg. Or for example: after purchasing my bike with the clipless pedals and shoes, I quickly proceeded to crash with the bike (failure to unclip) four times in the first week. I was ready to give up. But I had an extremely encouraging husband and a good friend, Dave, who would also be doing the triathlon with me. They kept me motivated. I not only finished the triathlon, but I came in 8th in my age group.
