Kiawah Island Marathon

The Kiawah Island Marathon is one of the Southeast's premier destination half marathons — a boutique race experience set on a private resort island near Charleston, South Carolina. Now in its 48th year, the course winds through maritime forests draped in Spanish moss, past grand homes and salt marshes, starting and finishing at the West Beach Conference Center. The flat, shaded roads make this a fast course despite the turns, and the December timing delivers ideal running weather with highs in the low 60s.

What sets Kiawah apart is the full resort experience. Runners consistently rave about pre-race yoga on the beach, a gourmet post-race buffet, and the festive Christmas market expo. Communication from organizers is top-notch, with shuttle service running throughout race day. The field is large but manageable — nearly 3,000 half marathon finishers in 2025 drawn from 44 states, with a strong female majority (62%). The median finish time of 2:12 reflects the welcoming, all-levels atmosphere.

This is a race worth building a weekend around. Stay on-island for the full experience (book early — accommodations fill fast) or base in Charleston for a more budget-friendly option. The half marathon is consistently rated 4.2/5 by runners, with especially high marks for race production and the island's natural beauty.
