I am preparing a 2-day rim-to-rim hike in Grand Canyon in fall 2019. This means that I will need to hike down 5,740 ft , 13.7 miles on the first day and on the second day I will need to hike up 4,340 ft and 9.5 miles in distance. I am looking for trails in the Pacific northwest that has similar one way elevation and distance that I can use for training. I do realize that it is a difficult match but if I can find one that has 2/3 the distance and elevation will be very helpful to my training. Also, it will be perfect if the beginning and end point of the trail can be reached by a road. I am thinking whether Mt. Rainier is a good place to look at because it is circled by Highways 706, 410 and 123 and vary with different elevations. Any info will be appreciated. Bobo1

Two hikes that come to mind are Sourdough Mt by Diablo Lake and Mt David by Lake Wenatchee - both a mile elevation gain.

I can't bring a perfect option to mind, but do keep in mind that an out and back trail will work for your purposes supposing you can go about 5k feet up in one roughly ten mile push. Just think of a single high point as your goal and think about your training as inverted. You don't need to hike down and back up to have trained - just hike up, then back down the same way. As long as the "top" is greater than your "shorter" day, that should help. Although it's never going to be as hot around here as it is down there and that is going to MASSIVELY impact your performance.

If you're in the Seattle area, there are many great trails off I-90 within 45 minutes of the city that can be used year-round for training. Tiger Mountain is one of the closer options. Cable Line and Section Line are both steep and get you around 2000' of elevation gain, but there are many other options as well, and you can loop different trails together to get as much mileage and gain as you want. Farther east you've got Mt. Si, old trail and new trail. The old trail is steep, gaining about 3300' in 3 miles, while the new trail is gentler, about 3200' in 4 miles. There are trails connecting them in the middle as well so loop options are a possibility here. Mt. Teneriffe is right next to Mt. Si and if you take the old Kamikaze trail you end up with about 4000' of gain in 4 miles to the summit, though the final section from the falls to the summit is almost a scramble at times and much steeper than these numbers imply. The new Teneriffe trail is logging road grade and gets you the 4000' over a much longer distance. Then of course there's Mailbox Peak. The old trail is a great workout, about 4000' in 2.5 miles, as long as you don't mind crowds and the 'circus' that has been discussed on this site. The new trail is much gentler but still gets you up there eventually. Of course there are tons of other hikes that more interesting than these ones but the ones I've mentioned are usually accessible year-round and fairly close by. Happy training!
