Oh, sure, it's where you're walking along trails or maybe without trails over different ground. It's not all even and perfect like a track or a road. I've had to do that for more than two hours before and it wasn't so bad because you felt like you were getting somewhere and it could be kind of pretty. So, maybe you can make the exercising more like that if you just try to imagine all the cool places you've been before and picture going through them while you do it?
