Being pregnant has made Barry's much easier (for now at least...)

I'm very newly pregnant and to my surprise Barry's has not only been fine, I've actually found it easier. I know that blood volume increases during pregnancy so I'm wondering if this one of the reason's why - I feel notably less out of breath when running and I find myself recovering much faster. I was particularly surprised as I came back after a 2 week holiday!

Anyone with a similar experience? I'm sure it will not be quite as easy as the pregnancy progresses though! (fingers crossed).
