The ladybugs, Eeyore (the Winnie-the-Pooh character) and the gender-less red blob were other noticeable figures who competed in Sunday's half marathon at Olympic Park.
"Pray for Japan"
Several runners wore T-shirts that said "Pray for Japan" on the back, including Seeichi Saito, who carried a flag identifying his native country as he ran the 13.2-mile half marathon.
Saito is from Yokohama and has many friends and family who live there. He said all of them survived the earthquake and tsunami that devastated the country more than a week ago.
His flag featured positive notes written in black ink from many of his colleagues and co-workers. He was worked in Atlanta for the past two years.
Running for a cause
The Brown family was another group of competitors running for a cause. Jeffrey Brown and cousin Hilary Ritter competed in the half marathon. Brown's son, Derek, competed in the marathon as part of his quest to run 50 marathons in 50 states to raise awareness of neurofibromatosis, one of the most common genetic disorders. Neurofibromatosis, also known as NF, can cause tumors to grow on the nerves anywhere at any time.
Brown's younger brother, Austin, was diagnosed with the disorder when Austin was 4 and living in their native New Hampshire.
With Sunday's event, Derek Brown has competed in 14 marathons in 11 states. His first was Chicago in 2005. Jeffrey Brown has run in 20 and Ritter four.
"When I'm out there running the only thing on my mind is my brother," Derek Brown said.
Austin Brown attends the University of Southern Maine, where he is on the golf team. He hasn't had any serious complications from NF.
"We just want to spread the word," Jeffrey Brown said.
