I dialled in some figures for the new Chatt course. My estimated Ironman Canada was pretty accurate, within 2 minutes. I adjusted my NP to match my actual NP at IMC and that got the figures a touch closer.

Having done that I used exactly the same setup for bike and rider, swapped out the course to Chattanooga and made the course 'Average Suburban' or whatever that option is (I used Mountainous for Whistler).

The Chatt Course is around 8 or 9km longer than Whistler but I am getting around 12 minutes faster than Whistler. Happy with that obviously but it seems like a lot. Are others getting figures that seem solid?

Should be a lot less climbing over the course.

No kidding, just didn't think it would make that much difference bearing in mind there is a lot less downhill too. More than happy though ... I'll hold you to it! :)
