At the risk of boring you, I offer yet again the approach I take to evaluating what gear is appropriate.

I cannot address your cycling-specific needs as I do not often cycle, and have no experience with commuter cycling since high school. I have never cycled into any wilderness more exotic than farmland, nor for longer than one long day.

But I think you might examine your kit against the Rule of Threes (you may die if you go: 3 minutes without air, 3 hours without shelter, 3 days without water, 3 weeks without food). And then I suggest checking to see if you have gear in each of whatever survival categories you salute; at this time mine include First Aid, Shelter, Fire, Water, Food, Navigation, Light, Signaling, Self-protection, Hygiene, and Morale.

If you used these criteria for a moment to review your kit, what would you see?
