The weather forecast for the day from Ubimet is a good one for flying, although it could get hot for hiking later in the day. For the areas of Tyrol and South Tyrol Ubimet forecasts some residual low clouds for dawn, then, “partly sunny and stable conditions during the morning hours with cumulus clouds building up towards noon.” That sounds like a classic flying day to us. 

“Later, isolated and slow moving or stationary thundery showers are possible above the mountains especially of East and South Tyrol as well as along the main ridge of the Alps. North of the Hohe Tauern the risk of rain remains low.”

It will be warm hiking through the valleys:

Max. Temperatures:
3000 m AMSL: 6°C
2000 m AMSL: 16°C
1000 m AMSL: 25°C
Valleys (~600-900 m AMSL): 26-28°C

And with wind from the north it could slow the athletes down who make the Turnpoint 4 at Kronplaz and then head towards Turnpoint 5 at Lermoos.

Wind conditions:
3000 m AMSL: gusts up to 30 kph from NW/N
2000 m AMSL: gusts up to 25 kph from N
1000 m AMSL: mainly diurnal mountain wind systems, hence daytime upvalley flow
Valleys (~600-900 m AMSL): mainly diurnal mountain wind systems, hence daytime upvalley flow
