Key West Half Marathon

Key West Half Marathon and Runfest spans two days in Key West, Florida, on January 16-17, 2027. Saturday holds the 5K at 7 a.m. and the 10K at 8 a.m.; Sunday brings the half marathon (13.1 miles) at 7 a.m., an 8K at 7:30 a.m. and the Beach N' Beer Mile at 3 p.m. USA Today has named the half one of the best in the country. Entry comes with a race shirt, a finisher medal and a race bag, and the weekend includes food and drink, a rum tasting and entertainment. A virtual option is available.

Stacking Saturday and Sunday is the obvious temptation, and a 5K or 10K the day before a half is manageable provided you run them as warm ups rather than races. If the half is your target, treat it as a proper goal race and build for twelve weeks with a long run that reaches 10 or 11 miles. The 7 a.m. Sunday start means an early alarm and a breakfast rehearsed in training rather than improvised on the day.
