This bra is seriously fantastic.  Best shape and most comfortable out of all the moving comfort bras I own (I have the fiona and the helena)!

However, I'm not sure it would be as supportive for running as either the fiona or the helena bras - it is perfect for hiking.  I am an avid hiker and this bra is amazing - absolutely perfect for hiking/backpacking.  Great shape (not squashed looking) and the straps are smooth and not bulking so your pack straps don't sit on top and dig into your shoulders (which is the case with the fiona bra and its bulky straps).  Also the back closure is much easier to navigate than the helena bra.

The ONLY minor downside is that the straps are a bit long.  If they could be adjusted a bit shorter it would be more supportive and possibly be ok for running.
