I like the One Touch Ultra Mini a lot and have a couple of them. They are great for running. On the recommendation of fellow member/ star of "Diabetic Athlete's Handbook" Jerry Nairn, I tried Race Ready shorts which have a mesh pocket that will hold the OTUM for 26.2 miles, which is very handy.
Re the CGM, I get pretty good results from the Medtronic CGM, I think that's your only choice other than Dexcom. The unit that is only a CGM is the same size as their pump (and I love my pump too...) but is very easy to clip to shorts, fuel belts or whatever for running. "Everyone" says the Dexcom is more accurate but the Medtronic one provides very reliable data for me and I've improved my BG control since I started using it in 2010. The Medtronic Carelink software is very easy to use and interpret data to identify trends with to make small adjustments. Although I dunno how that would work w/ MDI as I'm not sure that it's totally possible to do the fine incremental adjustments that one can do with a pump. Although I was always a big (literally...) "oh, I'll add a meniscus onto this unit of insulin to cover some "extra" which might be the same thing, if less precise. One other "fanboy" comment about Jerry, somewhere in his blog or homepage or something he has a pic of his Dexcom sensor taped to his arm for a race with packing tape. I prefer the Medtronic but that'd be an alternative. I saw the new Dexcom prominently displayed @ my endos the last appointment I had and was like "ooh, pretty colors" but I have no use for the extra gizmo. My belt is full and my pump/ CGM is clipped to it.
