Thanks xntrx for starting this very complete thread and asking some challenging questions. I've organized four economy runs near Montreal, which are a revival of the SMCC Economy Runs that took place at least as far back as the 1950s. To put things in context, Sports Motor Car Club (SMCC) Montreal is a road rally club and has know-how and insurance to run road rallies.
Let me bullet-list a bunch of take-aways that should be helpful for anyone thinking about organizing an Economy Run:
- start and finish in the same place
- use a service station with as many pumps as possible
- wrap up at a good-value restaurant at the finish, one that can seat everyone to encourage discussions
- work with a SCCA club if necessary to help with route planning, creating the instruction book and insurance (if required)
- work with a SCCA club or HAM radio club if you need checkpoints along the route (it's not always easy to find good checkpoint workers otherwise!)
- choose a route that is scenic/fun/challenging enough that people will want to run it year after year
- use the same route each year to encourage people to beat the previous result
- encourage local car clubs to come out in numbers to compete both against each other and for the overall prize (we've been able to create a small Club Smart vs. Ecomodder rivalry)
- couple the event with something else fun nearby the same weekend (we run alongside the F1 race in Montreal) to give an extra incentive for those coming from far, far away
If I had to say just one thing, it would be to make your event very distinct. For instance, the SMCC Economy Run is as much a driving challenge as an economy challenge, and it requires drivers to be sharp and know their vehicles extremely well in order to be highly competitive. That helps us attract competitive drivers and keeps the discussion lively at the finish. And it encourages mods that aren't purely for economy.
I think it would be great to see an event that is set up to allow for unbelievable economy, another with the most beautiful scenery, another which attracts the most audacious mods, etc. Again, I'd say "think distinct" to encourage people to drive hundreds of miles or more to participate.
Looking forward to hearing about more events! SMCC Economy Run will surely be held on June 7th, 2014 to coincide with the F1 yet again.
