What is the most interesting thing youâÄôve learned so far this year, in or out of class? Tracy Powell , a senior mechanical engineering and pre-med student, said through doing a triathlon she learned that âÄúif your will and desire are there, you can push yourself through mental obstacles.âÄù She recently completed the half Iron Man , which consists of swimming one mile, biking 56 miles, and running a half marathon. She did all that in just five hours and 50 minutes. Powell had been thinking about doing a triathlon for a couple years, but âÄúit took me a while to get the guts to do it,âÄù she said. The day of the triathlon, she said âÄúI donâÄôt think I can do this,âÄù but found that being on the course with all the excitement and adrenaline showed her she could push herself to a new level.
