Joabe Barbosa was pounding the pavement in a bumble bee costume Sunday for the Life Time Spring Half Marathon.
He's a graduate student from Brazil.
Barbosa has seta mission to run about 4,000 miles of Chicago streets that make up the city's 77 neighborhoods.

However, his visa was to expire in June, which would have cut his mission short.
But it was extended so he can continue his education at Roosevelt University.
Born in Brazil and raised in England, Barbosa went to college in Kentucky on a sports scholarship before moving to the Windy City a few years ago to pursue his doctorate in clinical psychology.
Barbosa often uses public transportation to travel to neighborhoods, running on average 10 miles a day, six days a week regardless of the weather.
Once the run is complete, he plans on submitting his accomplishment for official Guinness World Record recognition and maybe even take his run every street effort to other cities.
In January, Barbosa told ABC7 he doesn't really like running, but started it as rehab after surviving a life-threatening mountaineering accident in March of last year that left him with frostbite and hypothermia.
His doctor told him he needed to get his blood flowing, so since he couldn't play his favorite soccer every day, he took to the lakefront trails.
