There are many great races around the world but somehow we think there are a few ones that should be there and are not. With a bit of imagination it's not hard to set up a few races that would please many runners. 
The shortest ultramarathon
Running a ultramarathon is a dream for thousands of runners. When you manage 26.2 miles you start to question yourself if you could go a little further. A little, not 100 miles. No need to compete with Dean Karnazes. Is it too much to ask organizers to plan a 27 miles or a 43km race?
Paris half marathon. Underway
The half marathon in Paris is a great event and offers a superb sightseeing tour. But underneath the city there are hundreds of kilometers of abandoned limestone quarries. Is it really impossible to run through the catacombs of Paris? No need to stop the traffic for half a day either.
Folkstone to Calais
A tunnel of 31.4 miles could be an eccentric location for a challenging (I mean, a bit boring) ultramarathon. But if dozens of swimmers manage every year to cross the channel, some runners could conquer the Channel Tunnel as well.
10K with a great view
The Run2Sky Stuttgart is our favourite vertical race. Some other great runs are organized in many skyscrapers but (those engineers were not good enough) the fun is over after a few minutes. Could we add the challenge at the end of a 10K race in the London financial district?
The reflex challenge
Many trail races have - for safety reason - a minimum mandatory equipment to be carried for the entire race. We would welcome a city marathon where a digital camera is compulsory. Any runner crossing the finish line with less than 20 shots will be disqualified.
Move the finish line of the London Marathon
The Mall is a great place to finish the London Marathon. But if you move the magic line 200 meters west you could complete the marathon inside Buckingham Palace. The last few runners (cut off time is 7 hours) could enjoy a 5PM tea with the Queen too.
