This is a silly question that I hope someone who ran the Princess 2011 can help me with. Around mile 9? 10? 11? can't remember when! We were offered a small package of something that tasted like chocolate frosting. Is this what people refer to as "gu" or what is it? and where can I find it? I am running a local half marathon in 2 weeks (yikes!
) and I would like to pick some up for the race. It gave me that extra umph I needed. Thanks for your help!
