Black Rapid strap is good but not ideal for hiking without the backpack. Its better to bring your backpack and tripod even though its heavy especially if you are going to take landscape pictures.
I'll tell you, I'm petite and when I was 6 months pregnant I was able to carry 2 bodies(5d2,5dc), 3 lenses(17-40,24-105,70-200), accessories, tripod, waterproof overshoe, umbrella and snacks and I was able to hiked the Ricketts glen, Smokey mountain, Acadia, fingerlakes region and canadian Rockies. If I can do it, you can do it too
Good luck with your decision.
