Somebody Shut Me Up

Feeling a bit too hyper and talking too much about the marathon, training, nutrition, gels etc. and boring everyone around me so I'm writing here now to calm myself down. Came back from my personal training session and told some co-workers how my trainer thought I might be able to do this marathon in 4 - 4.5 hours based on the 10 miles I ran on Sunday and they agreed and made encouraging noises so I think that set me off and I could quite happily talk nonsense for the next 2 hours. So excited! However, I need to save my energy for tonight's big, hard, scary Interval training session. I've got lots to run and I've got to do it quickly, turning myself bright red in the process. So shooosh!
