Brandon:

I think Krizz has given you some good advice.  With mountain running we can just track distance.  10km with 1ooom elevation gain and loss is going to take several times longer than 10m with 300m elevation gain/loss.  It is best to distance and vertical. Use the time as a rough guideline.

I assume the 8400ft is gain and loss so you will end up where you started? If so the average grade is 10 32miles=169,000ft.  8400/169000= 5% but that is just if you only go uphill the whole way. If you go up 8400 and down 8400 the grade will have to be twice that 5%.  I would focus on the vertical requirement and let the distance fall where it may.
