Hi RM. There was a thread on this a while ago if you search jogging strollers or something similar. If you haven't already, check out the website www.joggingstroller.com/home.jsp There's a "stroller wizard" that can help you narrow down your choices. It is an American site so not everything will be available here but I found their reviews a big help when I was taking the plunge last year.
I've got a BOB (I'm a Yank and have a US postal address here) SUS D'Lux and love it. A friend (also American) just sold her BOB Ironman to another mumsnetter. It's fairly lightweight (for a stroller this size) and very easy to push. It's also narrower than a lot of strollers (I used to have a Buzz and the Bob gets in/out of shops easier). I'm a plodder/jogger, DH is the real runner and even he finds it easy. Of course the issue is getting one over here.
Babyjogger is another good, reputable brand (you can see all the love mumsnetters have for their City Mini which is our "every day" stroller) and available here (and no, I don't work for Groovystyle). While I don't know anyone with their jogging stroller, it was my 2nd choice based on reviews. I recall someone posted about their Baby Jogger jogging stroller about a week ago. Worth searching for the thread. They raved about it.
I don't know anything about the new Phil & Ted's. I clicked on the link and it looks cool and appears to have the right size wheels.
Whatever you do, don't get something with 12" wheels. You need at least 16" and if you're a serious runner, 20". You'll also want a fixed front wheel. If you have the opportunity to try it out, even better. Most have the rear axle sort of tucked out of the way but you might want to make sure it doesn't affect your stride.
The other thing I'd advise is to get the rain/weather cover that is manufactured for whatever stroller you choose. My American friend had one that fit her BOB and worked but mine which is BOB specific seems to fit better and is sturdier.
Hope this helps.
