It takes place annually on the second Saturday in April. The race was first run in 2008. In recent years it has become one of the most highly competitive ultra marathons in the United States. Registration Registration is limited to only 400 runners. As a result, entry into the race is determined by lottery. Race and elevation profile The Lake Sonoma 50 has a 14 hour time limit, with the gun-time being 6:30am on the day of the race. According to the official course website, 86% of the course is single track, 9% dirt roads, and the first 2.4 miles on a paved road. There are twelve creek crossings and around 10,500 ft of elevation gain throughout the race. Aid stations Stocked with normal ultra aid station fare including GU energy gels and products.

Lake Sonoma
Lake Sonoma is a reservoir west of Cloverdale in northern Sonoma County, California, created by the construction of Warm Springs Dam. Access from U.S. Route 101 is by way of Canyon Road (from the south) from Geyserville, or Dutcher Creek Road (from the north) from Cloverdale. The lake provides water for countywide growth and development, and for recreation. At full capacity, it has of shoreline, a surface area of more than , and holds of water. Activities include boating, swimming, fishing, riding, hiking, camping, and hunting. Notable features include the Milt Brandt Visitor Center, the adjacent Congressman Don Clausen Fish Hatchery, and the Warm Springs Recreation Area below the dam. History Pomo people had lived in the Dry Creek and Warm Springs region for over five thousand years. The construction of this lake completely destroyed 122 areas associated with the history of human use. This included ten house-pits, five hunting blinds, two chert quarries, and eleven locations ...

Hour
An hour (symbol: h; also abbreviated hr) is a unit of time conventionally reckoned as of a day and scientifically reckoned between 3,599 and 3,601 seconds, depending on the speed of Earth's rotation. There are 60 minutes in an hour, and 24 hours in a day. The hour was initially established in the ancient Near East as a variable measure of of the night or daytime. Such seasonal, temporal, or unequal hours varied by season and latitude. Equal or equinoctial hours were taken as of the day as measured from noon to noon; the minor seasonal variations of this unit were eventually smoothed by making it of the mean solar day. Since this unit was not constant due to long term variations in the Earth's rotation, the hour was finally separated from the Earth's rotation and defined in terms of the atomic or physical second. In the modern metric system, hours are an accepted unit of time defined as 3,600 atomic seconds. However, on rare occasions an hour may incorporate a positive ...

Minute
The minute is a unit of time usually equal to (the first sexagesimal fraction) of an hour, or 60 seconds. In the UTC time standard, a minute on rare occasions has 61 seconds, a consequence of leap seconds (there is a provision to insert a negative leap second, which would result in a 59-second minute, but this has never happened in more than 40 years under this system). Although not an SI unit, the minute is accepted for use with SI units. The SI symbol for ''minute'' or ''minutes'' is min (without a dot). The prime symbol is also sometimes used informally to denote minutes of time. History Al-Biruni first subdivided the hour sexagesimally into minutes, seconds, thirds and fourths in 1000 CE while discussing Jewish months. Historically, the word "minute" comes from the Latin ''pars minuta prima'', meaning "first small part". This division of the hour can be further refined with a "second small part" (Latin: ''pars minuta secunda''), and this is where the word "second" comes ...

Second
The second (symbol: s) is the unit of time in the International System of Units (SI), historically defined as of a day – this factor derived from the division of the day first into 24 hours, then to 60 minutes and finally to 60 seconds each (24 × 60 × 60 = 86400). The current and formal definition in the International System of Units ( SI) is more precise:The second ..is defined by taking the fixed numerical value of the caesium frequency, Δ''ν''Cs, the unperturbed ground-state hyperfine transition frequency of the caesium 133 atom, to be when expressed in the unit Hz, which is equal to s−1. This current definition was adopted in 1967 when it became feasible to define the second based on fundamental properties of nature with caesium clocks. Because the speed of Earth's rotation varies and is slowing ever so slightly, a leap second is added at irregular intervals to civil time to keep clocks in sync with Earth's rotation. Uses Analog clocks and watches often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sports In Sonoma County, California
Sport pertains to any form of competitive physical activity or game that aims to use, maintain, or improve physical ability and skills while providing enjoyment to participants and, in some cases, entertainment to spectators. Sports can, through casual or organized participation, improve participants' physical health. Hundreds of sports exist, from those between single contestants, through to those with hundreds of simultaneous participants, either in teams or competing as individuals. In certain sports such as racing, many contestants may compete, simultaneously or consecutively, with one winner; in others, the contest (a ''match'') is between two sides, each attempting to exceed the other. Some sports allow a "tie" or "draw", in which there is no single winner; others provide tie-breaking methods to ensure one winner and one loser. A number of contests may be arranged in a tournament producing a champion. Many sports leagues make an annual champion by arranging games in a r ...
