i need some opinions

I am thinking about signing up to do another March of Dimes walk. This one is in October, the 2nd to be exact. I will be almost 25 weeks pregnant. The walk is only .25miles long, which is one reason i am considering doing it. I of course am going to talk to my OB to see what he says about doing the walk that pregnant. So if anyone is reading this, would you consider doing that walk at 25 weeks pregnant (knowing my past).
