hi everybody, what I did was.
1 I use Caliber trainer first, and I use the steam compatibility.
2 activate both option from Cal trainer. ( as you can see Cal trainer does not have the green bar )
3 I close Cal trainer. Then activate the new trainer ( 0x90 )
4 press the option unlimited stamina.
now you can sprint all you want WITH OUT of worry of losing the green bar or slow down..
Spoiler:sure this may not work for the next update of the game. so for now enjoy it while you can, or till 0x90 fix his trainer...
