About 2,000 runners are expected to compete in the Lansing Marathon on Sunday. It includes a full 26.2-mile marathon and a half-marathon. There will be a 5-kilometer race and 1.5-kilometer children's event the previous day.
Police Chief Teresa Szymanski said people attending the Lansing Marathon will be protected. She said there will be additional patrols and bomb sweeps.
Szymanski asks that people attending the race to keep their "eyes and ears open" and report anything they think might be suspicious.
