Road v Turbo

[Stu Smith]

1 hour Turbo session coming up before my babysitting duties begin. Now that gets my HR up

Why do I feel like I'm having to put more effort into my turbo sessions to get less out...

Typical 2 Hours out on the road (Hilly North West ) average 15 - 16.5 mph Average elevation gain around 2,500 ft.
Average heart rate 150BPM..
Average cadence 95

Typical Turbo session not including interval training just the time on bike training when the weather as been to inclement to get out..
2 Hour session. 13.8 - 15 mph
Average heart rate 144 BPM
Average cadence 85
Does look like I'm putting more effort into the road sessions, but it feels like I'm having to put more effort in on the turbo to get less averages??

2 hrs on the turbo wow, a coach told me once 40 minutes on the turbo is worth 2 hrs on the road, I can live with that
