I am considering running a half marathon at the end of October. I haven't run for two weeks and it will be a further two weeks until I can run again. This is because I am currently fasting during the Islamic month of Ramadan. So I need to know if 11 weeks is enough to train for a HM. I have already run 10km twice within an hour and I would want to run a HM in about two hours. So what are everyone's thoughts???
