On the day of the shoot we met up early at 8am. It was an overcast day and it remained that way throughout the shoot. I welcomed the natural soft box that the clouds provided because it eliminated any harsh light that would otherwise be cast onto the couple. At the base of the hike I snapped a few test shots to get my settings and from there we headed to our first shoot location. Having checked out the area earlier in the week I broke the hike up into four rest/photo spots. This would ensure my couple didn't look as if they had run a marathon in their photos.
On a side note: photographing a couple who is willing to put in the leg work and hike is awesome for getting a great scene to pose at. I recommend packing some water for your clients. A little extra service can go a long way.
At our first spot I had the couple pose next to an old tree. I had them run through a few simple poses to get comfortable with the camera. I find having a couple start out sitting or leaning on something helps take their mind off of what their feet are doing and can allow them to focus more on engaging each other in a more relaxed way.
