Ultra-Trail du Mont-Blanc

The Ultra-Trail du Mont-Blanc is a single-stage mountain ultramarathon first held in 2003. It is a race of the Ultra-Trail World Tour, it takes place once a year on either the last weekend in August or the first weekend of September in the Alps, follows the route of the Tour du Mont Blanc through France and Switzerland. It has a distance of 171 kilometres, a total elevation gain of around 10,040 metres, it is regarded as one of the most difficult foot races in the world, one of the largest with more than 2,500 starters. It is one race during a week-long festival based around Chamonix in France; the races have strict entry and qualification requirements attained by accumulating enough race points through qualifying trail races over the previous two-year period. In 2016 and 2017, 42% and 34% of runners did not finish the UTMB race. While the best runners complete the loop in more than 20 hours, most runners take 32 to 46 hours to reach the finish line. Most runners will have to run through two nights in order to complete the race.

Since 2006, a second race Courmayeur - Champex - Chamonix has been organised, a third race was added in 2009: "Sur les Traces des Ducs de Savoie". A fourth shorter "running" event - Orsières - Champex - Chamonix - was added in 2014. La Petite Trotte à Léon is a non-competitive team event started in 2011; each team is made of three members for safety. The route and direction of the course change every year. In 2015, it was run counter clock-wise. Today, the races consist of the following; this is a loop around Mont Blanc. It starts from Chamonix and goes up to the Col de Voza to reach Les Contamines, the first life base, it climbs to the Croix du Bonhomme before going back down to Les Chapieux. The path runs up to the Col de la Seigne to enter Italy, follows the ridge of the Mont-Favre before going down to Courmayeur, the second life base, it climbs again to the Refuge Bertone and Arnuva before reaching its highest point, the Grand Col Ferret, which marks the border with Switzerland. The path goes down again to Praz de Fort via La Fouly before reaching the third life base, Champex d'en Bas.

The last part includes two rather low cols: Les Tseppes, separated by Trient. On the descent to Vallorcine, the path re-enters France and crosses Argentière before finishing at Chamonix, its starting point; the route varies every year, sometimes for safety reasons. In 2010, the route was 166 km long with a total elevation gain of 9500m. A more detailed profile can be found on the official web site: UTMB profile; the race's popularity and its entry rate grew since it was first held. The number of entrants doubled from 700 in 2003 to 1,400 in 2004. In 2005, the limit of 5,000 runners was reached. In 2006, the organisers decided to create the CCC; the registrations were sold out in only 2 weeks. In 2007, it was decided that runners must qualify, by running qualifying races beforehand gaining points; that year the limit of 5,000 runners was reached. For the 2008 event, 6,000 runners registered in 5 months before the race. For the 2009 event, the qualifying criteria were tightened to limit the number of qualifying runners, a draw was introduced to make entry fairer, giving an equal chance to all qualifiers, making registration more orderly.

Despite the stricter criteria, 10% of qualifying entrants were still denied a place, so the organisers raised entry standards still further for the 2010 event so that selection would be based more on capability and experience than luck of the draw. The races in 2010, 2012, 2017 were shorter due to bad weather conditions. 15000 volunteers were involved in 2015. Northface Ltd was the main sponsor from 2006 to 2014. Columbia has been the main sponsor since 2015. Kuala4k is the secondary environmental sponsor since 2014 Runners are supposed to carry a minimum of equipment for safety reasons; this includes a waterproof jacket, warm clothes and water, survival blanket and head lamp. There are drink points along the route, every 10 to 15 km. In addition, four big "life bases" provide hot meals and massages: Chamonix, Les Chapieux and Champex. At Courmayeur for UTMB and at Cormet de Roseland for TDS, runners can collect a drop bag they left at Chamonix or at Courmayeur. Runners' race numbers contain a magnetic badge, read at 50 check points.

It is conducted under the regulations of the International Trail Running Association, the governing body for trail races in the Mont Blanc and Alpine region. PTL is a self-supported run without course markings or aid stations. Runners rely on a limited number of support points, mountain huts, local stores and restaurants for food and sleep; the course should be followed by GPS, the road book. It g

Raymond–Summit Historic District

The Raymond–Summit Historic District is a historic district encompassing the 400 blocks of North Raymond and North Summit Avenues in Pasadena, California. The residential historic district includes 22 contributing buildings; the area was part of Rancho San Pascual prior to its development. In 1875, the Lake Vineyard Land and Water Company formed to manage the property; the company parceled out and sold the land and, between 1886 and 1904, the new owners built houses on their properties during a Pasadena building boom. Architectural styles represented among these homes include Queen Anne, Colonial Revival, American Foursquare, American Craftsman, Shingle Style, a number of vernacular styles. Prominent Pasadena architects Greene & Greene designed a Shingle Style house at 450 North Raymond and two vernacular cottages at 442 and 448 North Summit; the district was added to the National Register of Historic Places on August 9, 2011
