I've got a question for any of you that have CGM's. I just got my Dexcom today and started using it, so I'm really curious how others are using them during training. I'm looking forward to having it in my jersey pocket while cycling, but I'm a bit undecided on how I'll use it during runs. I'm thinking it'll be great to have with me on treadmill runs, but not so sure I'm gonna want to take it with my on outside runs. I have a thing about running with a lot of crap on me, it just doesn't feel right. Usually I'll bring a gel or two and thats it.
I'm on a medtronic pump so the CGM is no additional equipment other than the sensor. it didn't take long to get used to the pump being on my belt during an event.
For anything under 10km, just wear the pump/cgm. I don't carry a meter.
For 21-42km I may carry a meter in a spi belt but don't expect to use it.
Over 42km I am carrying a small pack anyway so carrying a meter as well doesn't matter.
I have the bayer meter (actually the newer model but the same size) and also the freestyle lite, both of which are quite small. Meter, lancet and a couple of test strips into a ziplock and into the spi-belt and I don't even notice it is there. the spi is also my race number belt.
