/ Using climbing rope for tug of war?
Have a work 'sports day' coming up - we don't have a rope for the tug of war (I know, I can't believe people don't have these lying around at home?!) so I offered my old retired climbing rope. Now I'm not too worried about the rope getting wrecked as I don't use it for climbing anymore, but will it hold the strain? likely to be a 5 on 5 game, but wondering if it may be safer to reduce the numbers...
A rule of thumb I have heard is the "rule of 12", that is, no more than 12 people pulling on a rope. Or 6 with x2 mechanical advantage etc.
For a tug of war, 5v5, the rope gets the same force on it as 5 people pulling on it if it were tied off on a post. So as 5 is much less than 12, I don't think there is any risk of it breaking, not by a long way.
It might stretch more than a typical tug of war rope mind...
I think a bigger issue is the diameter of the rope, and how difficult it would be to hold it. A typical tug of war rope is about 3.5 cm diameter compared to ~1 cm for a climbing rope. I can see the potential for a lot of burnt hands.
Cut it into thirds and plait it - will be much better to grip.
I was thinking of the stretchiness too. I imagine both teams pulling, moving backwards and the white hankie marker staying put.
Maybe you could lend them tiblocs for more grip?

Prussik loops for each "tugger"?
A relation of mine donated his retired climbing rope for the tug of war at the Queens Jubilee street party on his street in 1977.
The rope snapped, several injuries and one chap died of a heart attack.
And don't forget the chapess who topped backwards over the cliff and fell to death.
Knots in the rope?
Eek!!!!! Though that was 1970s rope right?!
Plaiting is a good idea and may help reduce stretch and likelihood of breakage - will have to check the length though. Otherwise knots in the rope should work. People should be bringing gloves so hopefully no rope burn!
It was an 11mm nylon Kermantle rope. State of the art back then.
Contact the Tug of War Association who should be able to advise you about obtaining a suitable tug of war rope for your event. Visit www.tugofwar.co.uk for info.
There's a helpful roundup of injury and amputation stories on Wikipedia:
ask these guys what to use - they might have a cheap cut off.
or the local scouts who might have thick laid rope that would be suitable.
If the "Further south than i would like" is anywhere near southampton i have one you can borrow
Thanks for the offer but I'm in London, so a bit far away! I don't really have time to get in touch to try and borrow one as its this week, but if the general consensus is it'll be unsafe then I may just have to retract my offer! But I reckon if it's plaited/twisted so treble strand it may be ok?
I'm in Dartford and have one you can borrow. I will sort it out and let you know how big it is.
It'll be fine. Unless you work for a scaffolding company i'd bet my house that 5 guys 'from work' cannot snap a climbing rope simply by pulling on it.
Ropes can take 2000kg upwards, so that'd be 400kg pulling power a head. And not just pulling, but having the grip strength to hold 400kgs, and the 10 people all have to be able to do so. I'd be surprised if there's 10 people in the whole world able to do it.
A single strand would be strong enough but hard to grip. If you plait it I think there's a risk of fingers getting snarled up in the rope.
Good lord, I had no idea tug of war could be so bloody dangerous!
It'll be fine. Just double it up and tell your tuggers to wear gardening gloves if you/they are worried.
