I've got three junked 10kg subcompact wheels. I've rigged a few up as a tire/sled drag:
- two tires on top of one another, linked by cheap bungee cords.
- currently "drag line" is 3m bungee I use doubled up, hooked through the bungee cords.
- the "handle" is currently a cheap 30kg gripper I don't use anymore. I'll upgrade it to a towel next time I drag, for better grip work and a surer grip.

The tires drag well but doesn't have that full-bottom friction that sleds do, but hey, a "real sled" would cost a lot more.
I'm not to sure about my materials, though. I plan to load the "bowl" on top with weight - probably a 20L old kereosene jug filled with water. I think the bungees on the tires will hold, not sure about the tow bungee. I'm concerned it'll snap and whip into my face, especially on a wide pull.
What's a good replacement? Should I get some climber's rope (if so, how thick?) or even go for chain? I can get 3 meters of 5.88 welded chain for around $10, plus a carabiner that'll hold 250kg for about $3. That would be indestructible for dragging, but I'd have less "play" on the cord for wide-grip or arms-apart drags or whatever. Am I worrying too much?
