Oh yeah. RoadID here as well. I forget about it because I just wear it all the time.

Hi piggy -- I keep my iPhone and my G4 receiver in the lower pockets on my MTB shorts (lower back thigh). You can't see it in the sunlight anyways, and I can nearly always hear the damned thing if I get too low.

I don't have a particular BG number to start from, mostly because my rides start much earlier than I'd normally be eating breakfast, so I grab a bite early in the morning, try not to take a large bolus, and hope the activity level helps boost the small amount of insulin I'll take. It usually works out well. Since my last few rides were literally "all day" 230 & 250 miles, I just take it as it comes, managing my sugars as I go by eating bars and drinking juice, and only taking very small boluses if needed.

Thanks for all the info guys.This is going to be the first time riding in a long time. For now it will be just around town. Michael where do you mount your G4 receiver on you bike, or do you? Thanks for all the great info.

Mountain biker perspective here:

• Shot Blox (several packs)
• Small bag of trail mix or a bar of similar stuff
• Dried Mango
• Backpack with 111oz. of water/ice (often with lemon)
• KIT: Pliers, knife, zipties, chain breaker + speed links, tire levers, tubes (of various sizes in case I run into someone stuck out there), handheld tire pump, lube, Stan's sealant (for my tubeless tires), sunblock, mylar 'blanket', tp, medical kit, extra derailleur hanger (if I have one)
• Couple of 'clean' rags...
• CHARGED iPhone (running the free Strava app)

All the above is what any MTB'er should carry -- yes, I do have basically an entire bike shop on my back. On top of that, I also wear my Dexcom G4.

I don't ride alone a lot, but one time I was and I didn't feel a low coming on. I was riding on a Sunday on a 4-lane road in an industrial part of town, and I began to lose focus. I think I was looking down at the white lines on the road rather than out ahead of me. Suddenly I looked up and found myself in the middle of the road! It's a good thing I was riding at a time when there was almost no traffic on that road at that time! I don't have a CGM yet. Man, that would have helped!

Comment by miketosh on May 27, 2014 at 8:46am

I target 150. On Saturday, I rode and the CGM was screaming "BELOW 40". Felt fine, figured it was at the end of its 7 days, so I Gatoraded up, and ignored the CGM. When I got home, the CGM was back up to 90-something, and tested within 7mg/dl. Yikes. I may have actually been riding with a below-40 bg.

A few long rides that I've done by myself, I texted my wife (concurrently driving) and her sister (where I was heading) at various points. I also fired up Garmin LiveTrack on the phone, although there was a large cost for that. I hear Glympse has the same thing but is a freebie app.

Comment by MikeMack on May 27, 2014 at 8:41am

Andy, I carb up b4 rides (I've pretty much figured out how much and when to eat pre-ride), set my pod on its lowest basal rate (.05), and sip on gatoraide, but I can still get a low every once in a while. It may be some insulin on board from an earlier meal or some other unknown factor. BTW, this is not normal, but it does happen occasionally. I find it a bit more difficult to feel an insulin reaction while riding, especially a lot of hills. Am I just getting tired or is my sugar low? Whne I start getting dizzy though, it's time to pull off and test. At what BG level do you try to start your ride with? I like to start around 180 if I can.

Comment by Andy on May 27, 2014 at 8:31am

Mikemack, for me the key is to reduce insulin so that there isn't a possibility of bottoming out. I never have bad lows while biking because of that, which is why I also stopped carrying glucagon. Even if I somehow ended up high (happens sometimes if I had just eaten a bar but then the group stops for 30 minutes), I'll just take a 0.5u dose for the hour.

Comment by MikeMack on May 27, 2014 at 8:23am

miketosh, your friend comment is important. Group rides are not only more fun and easier, but safer as well. We are much more visable when we are in a group. Also, my friends are very aware of my diabetes and know what to do if I get too low. Fortunately, they've never had to really do anything, except stop with me and wait while I test and treat.

I don't know about all of you, but I have to be careful not to saddle up too soon after a reaction. I don't like standing around and holding everyone else up, but it's dangerous to clip back in when I'm not above 100.
