Trek is a long, adventurous journey undertaken on foot in areas where common means of transport are generally not available. Trekking should not be confused with mountaineering.

The term derived from the Afrikaans word trek (noun), trekken (verb), (literally meaning to "pull, travel"), became a word in English language in mid 19th century, and means a long arduous journey, typically on foot.

The Himalayan routes are famous for attracting a large number of trekkers. Typical trekking regions in Nepal are Annapurna, Dolpo, Langtang, Manaslu, and Mount Everest. Other popular trekking routes in India include Chandra Taal, Gomukh, Hemkund, Kafni Glacier, Kangchenjunga, Kedarnath, Kedartal, Milam Glacier, Nanda Devi Sanctuary, Pindari Glacier, Richenpong, Roopkund, Sar Pass, Satopanth Tal, Saurkundi Pass, Singalila Ridge, and Valley of Flowers.

PHASE 2 (aka Lonny Wood) is one of the most influential and well known New York City aerosol artists. Mostly active in the 1970s, Phase 2 is generally credited with originating the "bubble letter" style of aerosol writing, also known as "softies". He was also influential in the early hip-hop scene.

Phase 2 is from The Bronx, and attended DeWitt Clinton High School along with a number of other early graffiti artists. Many famous graffiti writers of the early 1970s would meet at a doughnut shop across from the school called the Coffee Shop before heading down to the subway station at 149th Street and Grand Concourse to watch tagged trains on the IRT line pass by. Phase 2 was mentored in graffiti by his friend and neighbor Thomas Lee aka Lee 163d!, one of the pioneers of graf writing in The Bronx.

He began writing in late 1971 under the name Phase 2, a moniker which had a rather mundane provenance. As Phase 2 would later recall, "the previous year we'd given this party. We were getting ready to give another one and I said, 'We'll call this one Phase Two.' I don't know why, but I was stuck on the name. It had meaning for me. I started writing 'Phase 2.'"

Aaron Holmes Gwin is an American professional downhill mountain biker from Morongo Valley, California. He is recently known for breaking on to the international World Cup scene after about 8 months of riding downhill. Many see Gwin as the savior for US downhilling on the international scene since his 10th place finish at the Mont Sainte-Anne World Cup in 2008 was the first American top 10 finish since 2004.

Aaron Gwin started his cycling career off early racing BMX from age 4. By age 8 Gwin was racing all the nationals. At age 12 Gwin moved on to motocross and raced up until he was 17 when he quit due to constant injuries. In 2008 at age 20 Gwin was loaned a bike by fellow professional downhill racer and good friend Cody Warren and was encouraged to compete in a race. In his first race in the Fontana Winter Series he got 3rd and began racing from then on, quickly signing with Yeti Cycles. He has since won two United States National Championships for Downhill, in 2009 and in 2010. Both were held in SolVista, Colorado

Fabian Cancellara (born 18 March 1981) is a Swiss professional road bicycle racer for UCI ProTeam RadioShack-Nissan-Trek. A time trial specialist, he is a four-time World Time Trial Champion and is the current Olympic gold medalist. He is also a winner of Tour of Flanders, Paris–Roubaix (twice), Milan – San Remo, Tirreno–Adriatico, Tour de Suisse, Strade Bianche (twice), and four prologues of the Tour de France.

Cancellara was born in Wohlen bei Bern, a municipality near the city of Berne, Switzerland to an Italian mother and a Swiss-German father. He discovered cycling at the age of 13 after falling in love with an old family bike that he had found in the garage and immediately gave up football to concentrate on cycling.

Cancellara's cycling skills began to blossom at an early age, when he impressed as a time trialist and dominated Swiss junior cycling. Yvan Girard, Swiss national junior team coach from 1997 to 2005, was quoted saying that Cancellara was head and shoulders above everyone else in the time trials. He won the junior World Time Trial Championship in both 1998 and 1999 and at the age of 19 he came in second at the 2000 U-23 World Time Trial Championship, after which he turned professional with Mapei-Quick Step, then one of the strongest teams in the world.
