You need to have a very good level of fitness in order to participate. You’ll have to paddle for 11 days and there are at least 6 mandatory portages. You should be capable of carrying a heavy load (packs and barrels) or a canoe (75 lb / 34 kg). The portages around the rapids are in poor condition and will undoubtedly have poor footing and mud. Expect a number of portages every day at waterfalls, rapids, or canyons that you can’t, or would prefer not to, paddle. The longest portage is approximately 0.4 miles (600 m). The pace will be fairly brisk, but there will be more than enough time for instruction along the way. Although the rapids are not overly long, they are steep.
