The 2013 Iron—Man Match took place on a cold and windy day in Lake Placid.While my dad had spent months training，nothing could have prepared him for what he met on that day.

My entire family was there；however，I was supporting him from my summer camp，where I tracked him online.By 9：00 a.m.，my eyes were fixed on a dot on a screen that represented my father and his progress.He was making steady progress on the bike trail until all of，a sudden I saw his dot stop moving.I assumed this was a technical fault.After all，Camp Monroe Was not known for its Wi-Fi.Actually a gust of wind had caused a huge tent to blow into him，knocking him to the roadside.

At the hospital，he discovered he had four broken bones.While still recovering from his accident，he was dealt a second blow.He was diagnosed(诊断)with cancer and，although still weak from his injuries，had to suffer from accelerated radiation and surgery.His athletic future was looking more and more bare.

However，as he got better，he started to train again.Soon he was running weekly，bounding out of the house with a look of determination that both impressed and worried us.Much to our surprise，he just kept getting stronger.His desire to return to something he loved was greater than his expectation.Last summer，exactly three years after his accident，my father completed the Iron—Man once again.This time，he dashed across the finish line，his fist punching the air in celebration.

Now，I believe in the power of determination to beat the odds，regardless of the circumstance.Today，because of my dad，I believe in setting my own rules，and not letting others command what I can or cannot do.And I believe that life is just like that little dot；it can be gone in a second，so we must make every moment count.
