These beaches are large enough to be able to house cafes, restaurants and kiosks, but small enough to rarely be crowded. Malta's northwest is home to the island's quietest beaches, and it is on these that the main island's neighbouring two are nearest. Gozo and Comino are also popular beach spots for holiday-makers, although these are much more likely to be quieter, rockier and more suitable for snorkelling. The Mediterranean Sea surrounding Malta is popular for diving - while shallow dips may be attractive to beginning divers, more experienced divers may be able to dive deeper to find historical artifacts from World War II or earlier. Major event tourism, especially events centred on Catholicism, is an important segment of the Maltese tourism sector. During Holy Week, processions and religious services dominate the country and food stalls are set up in the village squares of Malta. Another popular major event is Carnival, a five centuries-old traditional celebration lasting for the five days preceding Ash Wednesday. Celebrations for Carnival involve float-based pageants, street parties and street food stalls. They are mostly Roman Catholic. One of the biggest sporting events held on the island is the Malta Marathon. Held every year in late February or early March, the race attracts a number of international competitors and has been sponsored by Land Rover since 2009, BMW from 2003 to 2008, GoMobile in 2002 and Flora Malta in 2001 and prior. In 2009, the full marathon winner, a Belgian, recorded a time of 2:25:59. In 2010, approximately 1,400 entrants participated. Since 2010, the Malta Tourism Authority has been marketing Malta as a medical tourism destination. Focus areas for medical tourism include "cosmetic surgery, orthopedics, ophthalmic, neurological, urological, oncology, diagnostic, bariatric and cardiac services." The focus target market for medical tourists in Malta is the United Kingdom, followed by North Africa, the Middle East, Russia and North America. Part of the reason for targeting the United Kingdom for medical tourists is that many members of Malta's medical profession were trained in the United Kingdom, increasing the confidence of British patients in those taking care of them. In addition, unlike some medical tourism destinations, Malta has a stable political climate. The Maltese government supports the development of medical tourism on the island but believes that private medical providers should be performing medical procedures, not government-run facilities. Educational tourism highly contributes to the number of yearly inbound tourists in Malta. In recent years Malta has successfully become a dominant country in the ESL (English as a Second Language) industry.
