In all honesty the best option to remove the diversion would be to put some temporary structure across the canal at the exit of the tunnel. I would happily pay an extra £1 in entry money in order to fund some kind of basic pontoon allowing the runners to cross to the other side of the canal.
Somewhat depressing that the diversion will still be in effect this year. Think I'll take the same approach as DarrenM. The main downside is that the diversion has a negative impact in two ways: (1) The nature of it means you'll slow down for that section, and (2) The diversion adds about half a mile onto the race distance.
Sadly that means an event which should have PB potential given the flatness of the route becomes much harder to run a competitive time on.
Did this last year while still injured and had a torrid time - the heatwave and that ridiculous climb up what seemed like 200 steps didn't help, and the start was a farce frankly.
Please tell me the diversion won't be in force this year? I feel like I have unfinished business with this race but the thought of the steps (which added about half a mile to the distance) puts me right off it.
