Local dad gives his all for Ironman; motivated by son battling cancer

Posted: Updated:
CHATTANOOGA, TN (WRCB) -  It's been about a year since Chattanooga Fireman Jason Greer signed up to race the Ironman competition, and was in no shape to compete in a bike race, swimming competition and run a full marathon.  But Greer said his son gave him all the motivation he needed.

 "I'm ready for it to be here, I actually wish it was this weekend," Greer said, "I'm ready to go."    
     
There have been 60 pounds lost and hundreds of miles gained since Channel 3 first introduced you to Greer in November.
     
Greer transformed his entire lifestyle and gained the confidence needed to finish a triathlon.

"I mean I knew I had a long way to go, I was severely out of shape," Greer said, "But I had so much motivation."
   
His motivation? Greer's 18-year old son Tristin.
     
At 13, Tristin was diagnosed with Stage IV Neuroblastoma. It's a type of cancer that affects the sympathetic nervous system and causes tumors.

"If I had half the willpower, strength and determination he has, this Ironman won't be anything," Greer said.
     
To prepare for the 2.4-mile swim, 116-mile bike ride and 26.2-mile run Greer teamed up with HUB Endurance trainer Andy Sweet.

"It's a roller coaster of a day, physically exhausting," Sweet said, "But then mentally you have to stay in check the whole day."
     
But his first impression of Greer wasn't that he was out of shape, it was that he already had the right mindset to cross the finish line.

"It's a sport that requires more discipline and determination than maybe physical fitness. Is it a physically difficult race? Absolutely."
     
In between training the family's been traveling to Michigan for Tristin's new treatment and his latest scans show improvement.
"Everyday for the past year I've envisioned crossing the finish line and then putting that medal around Tristin's neck you know because he's the real Ironman."

Greer said this triathlon is just the beginning. He's already signed up for another Ironman next year.

Greer is competing to raise money for both 'Emily's Power For A Cure' and the 'Make-A-Wish Foundation of East Tennessee'.
