Traverse through the main massifs of Gredos whose highest peak (Almanzor) stands at 2596 meters or 8517 feet. The route starts from Tornavacas mountain pass and climbs up to la Covacha (2389 meters). After this the route continues along the ridge summiting el Cancho (2271 meters) until you finally arrive to the Almanzor massif (the steepest and most magnificent area of the whole sierra). From here there's only the small hike up to barrerones and finally a walk down until La Plataforma (end of the traverse).

The Bay Circuit Trail is a 230-mile permanent recreation trail and greenway extending through 37 towns in Eastern Massachusetts, linking parks and open spaces in fifty-seven Boston area communities. Detailed maps are on the website. At the south end by Kingston you can choose either of the two options between the Southern terminus at Bay Farm and Tubbs Meadow Monroe Street Trail head (north leg or south leg). The gpx shows the southern option.

Mt Tam is generally done as an ascent time trial (to now FKTs are on the Strava segment). 

Another variation that has been reported is the most ascents in 24 hours - you must run down between ascents, but the last descent doesn't count towards the 24 hour limit (i.e., you can stop the clock at the last summit). 

Mount Daniel is the high point of King County, WA, and a frequently climbed mountain. The standard Southeast Ridge route begins at the Cathedral Pass Trailhead. Follow the Cathedral Pass trail for approximately 4.2 miles to it's junction with the PCT. Take the PCT southbound for about two tenths of a mile to the junction of Peggy's Pond trail. Follow this trail to Peggy's Pond then ascend the climbers trail on the SE Ridge of Mount Daniel. Follow this obvious ridge to the saddle below the East Peak of Mount Daniel and then traverse over to the West Peak and true summit of Mount Daniel.
