Ah, well, now that in itself is a topic worthy of long discussion.
Commercialism has indeed destroyed some sports, eg. football and boxing, has had a mixed effect on others, eg. cricket and rugby, but until recently outdoor pursuits of a running variety (ie. fell running, orienteering, adventure racing) have been relatively untouched.
For me, there will be enough room for all types of running - the cheap as chips local events for a couple of quid, right through to the huge overseas adventures which commercial companies are now putting on, in growing numbers, to cater for this market.
I love 'em all...... just wish I had more free time and money to do 'em all!
