Randall Siddens, 34, died Monday afternoon from injuries sustained in a May car crash on Grindstone Parkway, according to a Facebook post from his wife.
Columbia police said Siddens was hit by a Ford Focus driven by 23-year-old Regine McCracken while collecting traffic cones following the 2019 TriZou Triathlon.
Columbia police say McCracken was going 18 mph over the speed limit and was video chatting when she hit Siddens on May 5 near Bearfield Road.
Siddens is survived by his wife, Adrienne, and three children.
The Siddens family has a GoFundMe page set up to help with bills and long-term effects.
