Obviously I am (for those not in the know: start/finish is in my home town and slugbait is organising) Weather forecast is is favourable: dry, mild temperatures, head winds on the way out but only force 3 and stable so tailwind back.
The weather couldn't be more favorable (SE is the perfect wind direction), # of entrants is looking good.
When we did the route check a couple of weeks ago, it was during the final heatwave of the summer. The last 50k were horrible: 31 degrees, no shade at all, strong headwind. I could almost see my sweat evaporating from my skin. We had a couple of extra stops just to fill our bidons in a futile attempt to stay hydrated.
@QG: Since my talk at the start is going to be in Dutch. There are roadworks 20 meters from the start: I will ask everyone to walk along the sidewalk and to watch out when they rejoin the street. There are also two other obstructions in the final 1k, but you can easily get around this. The city of Groningen is in the middle of a big sewer maintenance project, so every week another street is temporarily less accessible.
