(although I think Ford will be there a while) I doubt it. IMO, they will walk at the first chance...or at least they should. It was a terrible marketing move for Ford while looking at bankruptcy in 2-3 years. Selling gas guzzler Exploders to six-figure trigeeks is not going to turn them around...neither is that terrible Mustang. It's a fringe sport and Bud Light would be a better target sponsor. It's all about increasing sales/revenue. According to the folks at AB, WTC dropped them. Expect Mich Ultra to take the podium for many triathlon events coming up.....
The retroactive clause is a valid question. Bud Light and Isuzu are still names I associate with Ironman. The Ford deal has been too aggressive, IMO.
Now...I'll take my "Degree" (had to put that in there) and offer up some FREE advise to Ford.....
Start an incentive to allow IM FINISHERS to use there medals for a $500 (rounded up entry fee) factory rebate. Take their picture at the dealership and post it right up on the wall. Start a website with Ironman finishers and their vehicles...start a "lifestyle" page and preach the benefits of having a utilty vehicle. Hell...there are MANY things they could do to lure folks in BUYING a Ford, but they just do the fluffy promotion crap.
