I don't know the answer but the description on the IM Chatt site says Specifically "2 loops 56mi (112 mi)" , I don't know if it was worded that way last year. I am signed up again for 2015 and hope they make the bike 112 and have no current for 2015.

The current rumor is that it will be changed to make it 112 for next year. Nothing official yet.

Why not prepare for 116 then you'll be so fresh when finishing 112 (or less). And while you're at it, no need to swim train for anything over 60 minutes.

Better get ready to run those hills.

I did the race Sunday as well as rode the bike course 4-5 times leading up to the race. I love the current course and liked that it was 116 miles ... made it something unique about Ironman Chattanooga. Personally, if I do the race again I'd be disappointed if it was changed.

Thanks guys, obviously wouldnt make or break doing the race or not, but wasnt sure what the plan was.

I did the race this year and will give them a two thumbs up. However, even if they were to come out today and say it'll be 112 miles, I would not put too much stock into what they say until summer of next year. The run course changed 2x this year. The bike course changed 3x, with the final time 2-3 weeks before the race. The start time changed a few times, with the final time during the athlete's briefing. The cutoff time changed shortly before the race. None of this should really throw you off your game, but it's one of those things that you should approach with a cautious attitude.

I am doing it in 2015 and I hope they leave it at 116, that way I can tell others that my IM was longer than your IM.
