This week, we spent some time with WikiProject Martial Arts. Since April 2004, the project has been the hub for discussion and improvement of martial arts articles, including all disciplines and national origins. The project maintains a variety of conventions for handling the names and descriptions of Chinese, Japanese, Korean, Vietnamese, Indian, Sikh, Filipino, Okinawan, and hybrid martial arts. WikiProject Martial Arts has spawned or absorbed several subprojects focusing on boxing, kickboxing, sumo, and mixed martial arts.

We continue our Summer Sports Series this week with WikiProject Horse Racing. Started in November 2005, the project has grown to include nearly 8,000 articles maintained by 34 active members. There are 10 Featured Articles and 19 Good Articles included in the project's scope. In addition to preparing articles for GA and FA status, the project attempts to create requested articles and locate requested images. We interviewed Redrose64, Montanabw, Tigerboy1966, Ealdgyth, and Cuddy Wifter.

With the 2012 Summer Olympic Games beginning this weekend in London, we decided to catch up with the chaps at WikiProject Olympics. The last time we interviewed WikiProject Olympics was in February 2010 when the project was gearing up for the Winter Olympics in Vancouver. We wanted to know how the project has grown since then and whether preparing for a Summer Olympics was more grueling.

With the Tour de France in its final week, we traveled to the French Wikipedia for a chat with Projet Cyclisme (WikiProject Cycling). The French Wikipedia places a greater emphasis on portals than the English Wikipedia, which explains why WikiProject Cycling and its discussion page are actually extensions of the Cycling Portal. The project is home to two Article de Qualité (equivalent to Featured Articles) and eight Bon Article (Good Articles), primarily biographies of cyclists.

This week, we spent some time with WikiProject Football, which focuses on the sport also known as association football or soccer. WikiProject Football is by far the largest sport project and one of the most active projects on Wikipedia in terms of the number of articles covered, edits to articles, and talk page watchers.
