Ignoring the 10% rule which is to prevent injury I ran 15K on valentines-day... it still hurts my right calf after one week. I posted my philosophy on the running times forum and got great advice from many kind people. As most, if not all, wrote that it would be better to build a base and forget about marathon racing in April, it gave me courage to give up my strive for running through pain in order to get race-ready. I knew it was difficult, and almost impossible to get physically ready by race-day in April, mentally I was (am) feeling very strong and ready to run the full marathon at any time.
Thanks to all you kind people out there, I have received your kind advise and will turn training back one nudge and contact the April marathon race committee to change my full marathon to a half marathon.
