'Map at the time of start' was tried once at SSS - I seem to recall there was an uproar and it won't be back anytime soon.
I understand older folks need to figure out how many/which controls they can get, but perhaps there could a special category for those who want to challenge themselves. That said, this particular race did not have a time limit - you simply had to got them all if you wanted to complete the longest course...
All the Melbourne ones you get the map at the start (and there's certainly a few old people...)
You don't have to plan :-)
