Stupid girl not running a marathon

Back at the beginning of the summer a friend asked me to train with her for a marathon. Wow...OK. Taking the advice of a friend who had run a marathon before we both purchase the Non Runners Guide to Marathon training and read it and followed it's training plan...Well...she followed it...I modified it to fit in my other activities including biking and swimming...STUPID...not to cross train...but to cut out some runs and replace them with other things...for example...a sprint tri every Sat for 3 Sats in a row while still increasing my long runs in the very same weeks...Needless to say I hurt my hip, recovered w/physical therapy and RICE then turned around to do one more tri, a 5K and then jumped back into my run training at the same place I left off. Oh yea then increased my mileage to what my friend was doing so I could be caught up. STUPID. On my second 16 mi run I felt great except my knee was hurting a little bit toward the end. It stopped as soon as the run stopped. Two days later I do a 6 mi run...my knee hurt the last half...next day I do a 9 mi run...knee hurt at mile 6 and for the rest of the day...this keeps going till me...Stupid girl... is limping around...find out it's my IT band...my running partner is doing 18mi then 20 then the taper and now I can't even run 6 mi w/o extreme pain for the run and next 24 hours....Yep...Stupid. We went to Logan Utah for the Top of Utah Marathon where she finished the Marathon with ease and I ran the 5K. The good news...I won 1st place in my age group...bad news? Only won because the fast well trained runners did the marathon!!! Well I cried while waiting at the finish line to see my friend cross...she cried too...for a totally different reason than me...but then again...I am the Stupid one...Pics to come soon! It's a great race...hope to do it next year For Real!
