hi carney,
i'm nearly in the same boat as you, particularly with the running...

how are you going with it? what is your routine now? much modified?

i did a 4ker and a 3ker as well as some walking but found I am just sooooo tired i couldn't do my usual 8k. the thought makes me sleepy. ireally wanted to be super fit and healthy through preg, but the 4ker nearly killed me... and i was only shuffling. and i'm only 5wks along! argh.

i think so long as you don't overheat and stop when you need to you are fine.

but for me, i'll keep a few gently ks a week in my routine but will be hitting the pool mostly, which isn't my favourite activity but i just have to bite the bullet, especially since i have back problems.

i'd love to hear what/how you've adjusted,
