The K-Swiss Ironman 70.3 Kansas is still looking for groups of volunteers to assist with Sunday’s race at Clinton Lake.

For groups of 15 to 20 who volunteer, Ironman will donate up to $500 to a nonprofit of the group’s choosing in exchange for volunteering. The race begins at 6:30 a.m., and volunteers are needed for various times during the event. For more information, send an e-mail to kansasvolunteers@ironman.com.
