John, John, John. You are simply missing the point; it's part of the buzz and attraction of mountainbiking, at least to those that partake in this particular pastime.
There is a direct correlation to the speed of decent, multiplied by a deficiency of braincells, plus the danger factor of falling off / hitting a wall / hitting you / slipping on cowsh!t and falling, all culminating in a compound adrenalin/enjoyment factor!
It's simple maths really.
I suggest you put some effort into hypothesizing as to how you can influence the outcome of any given mountainbiker's experience at the point of passing your gaff. I'm presuming you live at the bottom of a hill for them to be passing at this presumably antisocial velocity?
Maybe some fishing wire strategically stretched between 2 points accross the path? You would need to cater for severed limbs and the possibility of facing a manslaughter/murder charge however.
Too harsh? Ok, maybe invest in some ducks and let them poop on the path at a suitably relevant frequency? That ducksh!t is slippery as f*ck and should dispatch the lycra-clad pedal-heroes most effectively!
What about some military flashbangs? Or if you're feeling more adventurous some Claymores? Those things will disrupt their foot/pedal interface in the most efficient way imaginable! We may potentially be back in the realms of manslaughter/murder however.
For maximum effectiveness, perhaps you could mobilise Mrs. John into baking some nice cakes laced with a strong laxative. Invite the bikers to stop and partake of a slice and a cuppa and then send them on their way again.
20 minutes down the road and they will be struggling to de-lycra in a most unseemly fashion in order to vent the contents of their bladder/bowels?
You really need to start thinking pro-actively rather than complaining John!
