Some folks do the eastern leg as and out and back..very flat terrain. If you do the eastern and western route..the western has a few more hills..see the elevation plot in the link above. It may look 'challenging', but remember this is over nearly 200 miles. 3000 feet of elevation over 200 miles is pretty much nothing. RWGPS doesn't identify any climbs of any significance.
What kind of gearing does your Giant have?..if it's a fitness-hybrid..I'm guessing reasonable enough to get you started.
oops..I had the above link set to "private"..the link may not have worked..it's open now.
