how to be in the guinness book of world records
Guinness World Records For many records, Guinness World Records is the effective authority on the exact requirements for them and with whom records reside, the company providing adjudicators to events to determine the veracity of record attempts. The list of records which the Guinness World Records covers is not fixed; records may be added and also removed for various reasons. The public are invited to submit applications for records, which can be either the bettering of existing records or substantial achievements which could constitute a new record.[2] The company also provides corporate services for companies to "harness the power of record-breaking to deliver tangible success for their businesses."[16]
100 metres The 10-second barrier has historically been a barometer of fast men's performances, while the best female sprinters take eleven seconds or less to complete the race. The current men's world record is 9.58 seconds, set by Jamaica's Usain Bolt in 2009, while the women's world record of 10.49 seconds set by American Florence Griffith-Joyner in 1988 remains unbroken.[note 1]
