Are you on the road?
If you pass a sporting goods store, get some skiing mittens or some hippohands (which is what the snowmobilers use). If you pass a military surplus store, get some trigger-finger mittens that will fit over your existing gloves. They're ugly & cumbersome, but also cheap & effective when your hands are only needed for holding onto the bars and squeezing the brake.
Not sure how this will be received, but when I used to get stuck riding in sudden snowstorms in Colorado, I used to sip a shot or two of peppermint schnapps. (Yes, I'm aware of the dangers of drinking and driving.) It must do something to keep the blood thin and circulating, because it definitely helped me when the cold was bad enough to wake up my old frost-bite injuries.
Ride safely and good luck!

Sounds like a fun ride, i once drove 1200 miles in 10 hours. Yeah thats a bit of speed andf i even had a diferential blow up and had to push my car the last 5 blocks. Anyway after that i realy dont think i want to do another enduro drive much less and enduro ride. My hats off to you guys that can pull those rides off. Oh and Chris i wont encourage drinking on the road but i do know what you mean, i used to do the same thing 4hweeling in the mountains when my trucks heater whent out...

 

I've done 85-90 on an 1100 miler and best I could do was 15. Hats off too ya, just cant figure out what could have made that differential go out(smell the sarcasm lol)

 

My Gerbings are in the shop. The left one went dead last Tuesday on the way home from work. So out come the Hippo Hands. Not to bad. Nothing beats electric gloves though!
