This is something that I wrote some notes on around the London 2012 Olympics, and just sitting here watching the Men’s Road Race on day 1 of Rio 2016, I thought I’d dig it out and finally post it.
Competitors have to ride stock bikes — no fancy superlight frames or custom wheels; just ordinary commuter-type bikes. They can be set up for the individual, but they must have mudguards and lights and EITHER a rack and one pannier OR the competitor must carry a backpack or messenger bag; the bag to hold a weight equivalent to (say) a laptop and a change of clothes.
The race to be a typical commute distances (say 5 miles?) carried out over normal commuting streets, during rush hour, with normal traffic.
Competitors get disqualified for jumping red lights or going the wrong way down a one-way street; and receive time penalties for going on the pavement (maybe disqualification there too, actually). They may receive a time bonus (or at least clock-stoppage) for unreasonable delays, as for example when an articulated lorry is reversing across the road and holding everybody up.
To be run as time trials with say a one-minute separation, so competitors should not be directly racing against each other.
An alternative version would have them use bikes from the city’s bike-hire scheme. They’d have to turn up at a designated pickup point, wait if a bike wasn’t available, and so on. This has the added advantage that it forces host cities to have or introduce such a scheme, and to keep the bikes well maintained.
It’s challenge that normal people — ones who commute by bike, at least — could really identify with.
