Cycling through lightning?

Me and Son aged 9 are off on our first camping tour tomorrow. Theres thunder storms forecast for tomorrow and frankly, I'm bobbing myself.

What are the do's and don'ts when cycling out in the open when it's lightning?

Got to the point where I'm considering cancelling the trip.

You will be fine. Just stop somewhere safe to shelter as it passes.

Our route tomorrow is on the high peak trail, its a disused rail tack on a cutting above the surrounding country -
We're going to be high up, there's no shelter and we're attatched to metal things. Surely this isn't good?

OH has suggested DRIVING streight to the campsite - he's either worried or jealous!

Buy a carbon fibre bike, it won't conduct electricity, however it might melt in the rain :wacko:
Seriously Sara, you'll be fine :thumbsup:
Quite a number of fishermen killed when their carbon fibre rods touch overhead power lines might just disagree about the non conductivity of carbon fibre.

I read a while back not to shelter under trees, supposedly where theres not metal structures around they act like a big lightning rod attracting lightning and the lightning will arc from the tree through the person for a more conductive route to earth, id always thought it was just incase the tree fell on you! Im probably the worst person to offer advice only a few years ago having waited for storms for good winds to go power kiting :crazy:

If youve got a smartphone www.raintoday.co.uk is very useful for watching what the rains doing though :smile:

Lightning doesn't have to strike you directly to cause an injury or fatality. It can strike the ground (or a nearby tree/object) and still cause a fatal shock. It would depend on the strength and proximity of the strike and on where and how you are standing.

When lightning hits the ground it dissipates very rapidly in a generally hemispherical shape and during this process sets up equipotential lines across the ground in the form of an electric field. If you happen to be standing in the 'wrong' position across these electric fields then you could conceivably be electrocuted.

I believe there have been recorded incidents where this has happened, to farm animals and people on playing fields.

Fortunately, I would think that the probability of such an occurrence is very very low indeed. You probably have more chance of winning the lottery jackpot.
 
I would have thought the tyres would act as insulators thus providing no way to earth. Having said that the voltages involved are huge.

Tyres wouldn't help very much from a direct strike and wet they would be even less help. I'm not sure but I think 20KV can arc across about 1cm of dry air so half a million volts should have no problem with bike tyres. Then again if you are near to a better conductor may be the tyres will help, who knows.

Your second sentence is they key. Air is also an insulator under normal conditions, but when faced with a zillion volts of thundercloud, it conducts as well as Simon Rattle. So 28mm of tyre won't make a jot of difference.
