I really like 32GI but the lack of information on there website on my specific needs for long endurance races is zero. I have send them two e-mails to find out if my understanding of fueling on a half ironman and full ironman with 32gi products are correct but no responds. It is a pity because I still think it is a good product. Anyone fueling on Hammer because I think I'm going with them from now on? There website has so much information and very specific to endurance and ironman racing.
