Workers on Saturday put the final touches along the race course for the 34th annual Nationwide Children's Hospital Marathon.
Part of the setup include new security measures to keep atheletes and spectators safe.
Sunday's marathon will be Jim Arnold's second race this year. He says he welcomes the new security measures as Boston's marathon bombings are still very fresh.
"In today's world you have to be a little bit worried but basically you have to do what you have to do," Arnold said.
Organizers told athletes the new rules were instituted to create as safe an environment as possible. No large bags will be permitted in the bleacher area. Athletes are only allowed to check clear bags. Only athletes are permitted on the race course and finish line.
Josh Horning and his family traveled from Indiana to participate in the race.
He says right after the bombings in Boston, they had reservations, but they're confident in Columbus security.
"It was something we talked about after it happened just a little bit but coming here it seems like it's a safe city and we don't want anybody to hold us down," he said.
This is the seventh consecutive year the marathon has sold every last spot in the race.
18,000 athletes will compete.
