I would do what you can until as long as you can. General advice for us mere mortals is reduce by 50% and keep your heart rate below 140, but I think if you're an accomplished runner you can do more. Before pregnancy I was a 70 miles plus a week sub 3 hour marathon runner.
I am pregnant with twins, now 33 weeks, and walked/jogged up till 26 weeks, but then the weight of the two little rascals became too much and needed to stop so much for the loo it wasn't worth it. I was doing up to 6 miles 3mins walk, 3 mins run, heart rate going up to 155, but then my body was pretty used to intensive training before I got pregnant. Was also going swimming 2-3 times a week covering 1.8-2km.
Now at 33 weeks, I am pretty much reduced to a 3 mile walk and the odd swim, so doing something nearly every day, but do find I am very tired and doing too much makes me quite sick.
My babies are doing very well, a good weight, so am really pleased given I am a tiny person. My blood pressure is very low and the walking helps with my swollen feet. So I think trying to keep up some sort of activity is envaluable.
