okay, hear me out on this and please be kind with any comments that you might decide to leave. I am an avid long distance runner and I have logged 40-45 miles of running a week for the past 2 years. I am currently 6 weeks pregnant and completed a half marathon yesterday. I'm registered to run a marathon when I am 17 weeks. I will of course ask my doctor for advice but do you think I should still run it so long as I'm having a healthy pregnancy with no complications and my doctor approves?
