Exeter hooker Jack Yeandle says the club will not take their tournament with Bath and Gloucester lightly.
The sees the three clubs play home and away as they prepare for the Premiership campaign, which has been delayed until the middle of October because of the World Cup.
"You need to hit the ground running when the Premiership comes round," Yeandle, 25, told BBC Sport.
"You can't just ease into it or else you'll definitely get found out."
Yeandle, who is recovering from a back injury, says the games will be intense as they are local derbies.
"They're always real battles," he added. "It went each way with Gloucester and the same with Bath, and that's kind of the level that the games are at between us, that they can go each way both home and away."
