I've got a fixed gear 29er that I use for commuting, but now that the weather's getting summery I want to start taking it out on trails outside the city. I've never ridden fixed on trails but I hear it's quite a ride. My problem is pedals. Right now I use MKS commuter pedals with toe clips/straps, which I wouldn't want for trail riding in case I have to bail off my bike in a hurry. But clips/straps is how you slow down a fixed bike, so...

I've got good disc brakes on the bike, do I just get platforms and use the brakes to slow down? Is there another option? PS I don't want cleats or a clipless setup
