I think one of the demands from ASO was that it had to involve Copenhagen.
Otherwise... why not have the Grand Depart in Århus? Århus is a nice city. We have hills.
I think the Grand Depart is very convenient and sensefull to place in Cph. I like that.
But from there on, plenty of missed opportunities to do fireworks, though the final including the Great Belt Bridge is a fine opportunity.
However, 3rd stage could easily be a complex hilly stage with a hilly final sprint (more hilly than the one in Sønderborg).
Could be in city center or in outskirts of Vejle, Aarhus, Randers, Kolding, Silkeborg, Horsens, Hobro, Skanderborg, Aabenraa, etc.
Lived in or next to most of the places myself during the last 5 decades, vacuuming the hills in the surrounding landscapes with my bikes
But even Tour of Denmark avoids all the fine opportunities - and even the Queen stage in Vejle is mostly decimated to the final three laps round Kiddesvej due to the peleton hesitates in all climbs before the finale (nb: at least five climbs in or around Vejle are harder than Kiddesvej).
So even ppl in flatter parts of Denmark thinks our country only can deliver "speed bumps".
Theres a heck of possibilities to make a Danish version of AGR.
