Road closures and maps for Saturday's Ironman

KONA (HawaiiNewsNow) - Saturday is the Ironman world championship in Kona on the Big Island.    

The world's most fit men and women will tackle the course. Its 2.4 mile ocean swim, a 112 mile bike ride and a 26.2 mile run. Nearly 18-hundred athletes have signed up.  

Motorists are reminded of road closures and detours during the contest.

Drivers are urged to use extra caution, be aware of runners, bikers, pedestrians and spectators, and to anticipate traffic delays.

Ironman Weather Forecast:

Expect upper 70s at the 7am start, then quickly warming to the mid-upper 80s as the morning progresses.

Winds will be easterly or off-shore for most of the morning, but turn on-shore late morning. That westerly flow will strengthen and gusts could reach 35mph by mid-day.

That means middle of the pack bikers will have a fight on their hands as they navigate their way to Hawi and back. The wind should calm as night falls and the cooling temperatures will be welcomed by those still out running the marathon route after dark.

Good luck to all participants!
