Ten Tors Ten Tors is an annual weekend hike organised and run in early May for 2 , 400 young people by the British Army on Dartmoor . The majority of entrants are schools , colleges , Scout groups and Cadet squadrons from South West England , though groups from across the UK regularly take part , as do teams from Australia and New Zealand , though from 2012 onwards only teams from the South West of England will be able to take part , due to the high numbers of entrants . Event format . Teams of six are required to visit ten tors ; on the top of each tor is a checkpoint . Up to two members per team may fall out during the Challenge ; if a team drops below four members they may ' join ' with another team walking that route . If joining is not possible the team will be ' crashed out ' of the event . Ten Tors Charter 2012 , Annex E , para 25 There are twenty - six different routes over three different distances lettered from A to Z , using a total of nineteen different manned tors : twelve Bronze routes of for those aged 14 to 15 years , ten Silver routes of for those aged 16 to 17 years and four Gold routes of for those aged 18 to 19 years , or 17 - year - olds who completed a Silver route the previous year . Teams normally train for a few months before the event . The organisers stress that the event is not a race – although teams often compete to see who can finish first – but a test of endurance , navigation and survival skills , not just because of the distances and the challenging terrain , but potentially the weather : conditions on Dartmoor can vary considerably and change suddenly . In 1996 , for example , the event was struck by a heavy snow storm , leading to some teams still being out on the moor a day after the event was supposed to have finished ; in 1998 temperatures reached 26 °C ( 78 °F ) . Participants arrive at Okehampton Camp on the Thursday or Friday before the hike , watch a safety briefing video and have their equipment checked , a thorough process known as scrutineering . Teams must carry all their food , clothing , tents , stoves , fuel , navigation equipment , maps , emergency rations and a first aid kit ; they also collect drinking water from the moor and use water purification tablets . Each team has a nominated team leader , who is responsible for ensuring that the team ' s routecard is stamped at each tor . All the teams start at 0700h on the Saturday from an area of flat land next to Anthony Stile , close to Okehampton Camp on the northern edge of Dartmoor they stand in a semicircle and set off when a cannon fires . They have 34 hours to visit each of the ten tors on their route in the correct order . Teams cannot pass through a checkpoint between 2000h on Saturday and 0600h on Sunday morning ; nor may they pass the ninth tor ( eighth for the 35 mile route ) until the Sunday . Those trying for a Bronze medal must camp at one of the manned tors on their route , while Silver and Gold teams can camp anywhere on the moor . Teams must finish back at Anthony Stile by 1700h on the Sunday , having visited all ten tors on their route , in order to qualify for a medal . History of the event . The first Ten Tors Expedition took place in September 1960 , with around 200 young people taking part . By 1980 , the numbers had grown to more than 2 , 600 . To protect the environment , the numbers are now limited to 2 , 400 individuals - 400 teams of four to six teenagers . The Army uses the event as a large scale logistics exercise . Until 1967 the event was organised by the Junior Leaders Regiment , Royal Corps of Signals . This responsibility passed to Headquarters South West District , and in 1986 to 43 ( Wessex ) Brigade , the regional Headquarters of the Territorial Army in the South West . Many military units and civilian groups provide support for Ten - Tors and the Jubilee Challenge including the Royal Wessex Yeomanry , Exeter UOTC , 243 Field Hospital RAMC , 6th Battalion The Rifles , two Sea King HC4 helicopters from 848 Naval Air Squadron , 39 ( Skinners ) Signal Regiment , two Gazelle helicopters from 7 Regiment Army Air Corps ( Volunteers ) , Bristol UOTC and the Dartmoor Rescue Group . Since 1977 an additional event , The Jubilee Challenge , has been held for young people with physical or learning disabilities . This involves a selection of four routes of between , both on road and cross - country . 1981 . First ever Junior Army Team from Junior Leaders Regiment Royal Armoured Corps JLR RAC finished the Gold Course with 24 minutes to spare . The six - man team who refused to give up , despite several of them having severe foot injuries , were cheered home by an honour guard of Royal Mariners and Paratroopers who walked with the boys over the last mile . 1993 . Tavistock Times reports " Hurricane Force " winds during the event . 1996 . A cold northerly wind on the Saturday of the 1996 event turned to rain and snow overnight . This continued through Sunday , accompanied by fog and driving wind . Requests from Tor party commanders , two of which had their tents destroyed , added to pressure to abandon the event and a mass evacuation of the moor went ahead on the Sunday afternoon , the first time the event had been terminated early . Fifty one teams completed their routes , but no record remains of their success . Ten Tors , A History 1997 . The was the 1st year that Tavistock & District Youth Forum entered a team , a 55 mixed team who all finished . The team leader was Helen Blackburn , with Peter Challiss as team manager . 2001 . Ten Tors was cancelled in 2001 due to the foot and mouth crisis , but went ahead the next year . 2002 . Traditionally on the morning of the event a number of songs are played over the loudspeakers . Favourites are " Chariots of Fire " , " ( Simply ) The Best " , " In the Army Now " , " These Boots Are Made for Walkin ' " and " I Will Survive " ; in 1986 Cat Stevens ' " Morning Has Broken " woke the tented village at 0600h . In 2004 the CD line - up was changed , to large uproar and complaints ; it reverted the following year . 2003 . For the second year in succession the Plymouth DofE Award 45 team took the honour of leading the teams over the finish line , at 08 : 49 ( Ten Tors Teams , 2003 ) , improving on their time of 09 : 23 in 2002 ( Ten Tors Teams , 2002 ) 2004 . In 2004 the Ten Tors record for earliest complete team home was broken by R1809 , Dartmoor Plodders , with a time of 08 : 19 . This stood until 2009 . 2005 . In 2005 , one of the original teams from the 1960 Ten Tors took part in the event , which was held on 14 – 15 May in particularly adverse weather conditions : constant rain on the Saturday , combined with a bitter wind , leading to an unusually high number of retirements . 2006 . In 2006 , the event was held over the weekend of 13 – 14 May , with high temperatures on the Sunday resulting in several cases of dehydration . 2007 . On Sunday 4 March 2007 , Charlotte Shaw was swept away by rain - swollen Walla Brook near Watern Tor , while training for the event . The rest of her group raised the alarm using a mobile phone , but despite being evacuated by a Royal Navy helicopter within 20 minutes , she died later that night in Derriford Hospital , Plymouth . In December 2009 an inquest into the death was halted for the case to be considered for criminal charges . Several other groups were also evacuated by helicopter after weather conditions in the training area , Dartmoor National Park , deteriorated . The decision was taken on Saturday 12 May 2007 at 21 : 30 to abandon the actual event half - way through as a result of severe weather conditions ; the decision was influenced by the high drop - out rate of 15 % on Saturday . Participants spent the night camped at a manned Tor , before being escorted off the moor by the military the following day . 2008 . From 2008 the event was much changed with different routes and use of the moor itself to help bird conservation in the nesting season . Steeperton Tor and Hare Tor were dropped from the Tor list , and the pass from Dinger to Kitty Tor known as " Death Valley " was zoned off limits . Each team was permitted only two training walks on the North moor . A review of these changes . The 2008 event was the complete opposite of the previous years , with temperatures in the low twenties C , and participants dropping out because of dehydration rather than hypothermia . The first team across the line was the 20th Torbay Explorer Scouts finishing at 09 : 10 . 2009 . In 2009 the Ten Tors ' record for the earliest complete team home since the rule change was broken with a time of 08 : 17 by 20th Torbay Explorer Scouts . For the first time an all - girls team , from Torquay Grammar School for Girls also broke the record for successfully completing the 35 - , 45 - and 55 - mile events consecutively and with the same team members ( Tamsin Owen , Joyce Nie , Francesca Hill , Amelia Skerritt , Rebecca Stanley and Hannah Short ) . There were fewer dropouts than in other years in almost perfect weather conditions . 2010 . 2010 saw the 50th anniversary of the Ten Tors event . To mark the occasion the Duke of Edinburgh visited the event on Sunday morning to speak to finishers and present some with the commemorative 50 years medals . It also marked the first year that teams carried a GPS tracker which enabled the organisers and team managers to track the participants ' progress directly . The first finishers were 20th Torbay Explorer Scouts ( Joshua Owen , Matthew Ryder , Luke Hayward , Jacob Shah , Paul Moroz and William Fordyce ) and King Edward ' s School Bath who walked over the line together at 7 . 37 to break the record for earliest finishers by 40 minutes . This also meant the scout group had crossed the line first for three consecutive years . Notable other finishers were the ' Denbury Boys ' who , made up of men who completed the first ever Ten Tors , successfully completed the 35 mile event . 2011 . The 2011 Challenge started under a clear blue sky , but cloud obscured the tops of * West Mill and * High Willhays even then . Cloud and a fresh breeze built up through the day , but by 17 : 50 a blue sky was breaking through . Sunday was very similar with the first finishers ( M1306 - Downend Scouts , at 08 : 35 Route M listing , 2011 ) walking in under a blue sky , but again the cloud gathered through the day . Notes from the Event . The largely overcast and cool weekend was almost perfect walking weather - of the 390 teams which started 374 ( 95 % ) walked over the finish line , and of those finishing teams 316 ( 81 % ) walked in with all six team members . Over the last fifteen years of the event this is the highest percentage of both Finishing and Complete teams . Sixteen teams either retired ( just 7 , less than 2 % ) or were ' crashed out ' , but even here the statistics are impressive – in the previous 15 years teams are noted as stopping at their second Tor onwards . In 2011 the first teams to stop reached their fifth Tor before doing so . It was also the 50th anniversary of Dartmoor as a National Park so everyone received a participant certificate . 2012 . The first team to reach the finish line was the Torquay Boys ' Grammar School 45 - mile team , who reached camp at 8 : 56am . They were soon followed by both Torbay Explorer Scouts and Queen Elizabeth ' s Hospital School 45 - mile team , who performed an excellent display of sportsmanship by finishing the last kilometre of the course side by side , despite a failure in the alarm of the QEH team , delaying the team by a full hour . The first all - girl team to reach the finish line , The Maynard 35 - mile team , got back to camp at 10 : 20 , setting a new time record for the school . The Maynard 45 - mile team also completed the challenge in a respectable time , finishing at 13 : 59 . The 2012 event was notable for the selfless efforts of one team , X2414 Kingsbridge Community College ( 55 ) , who were on schedule to complete their route shortly after 16 : 00 when they diverted to answer the distress whistles of another team which had two of its members trapped chest deep in Raybarrow Pool . After calling in the Dartmoor Rescue Group and helping the other team , X2414 walked in at 17 : 19 , almost twenty minutes after the close of the event - this would normally debar a team from receiving their awards . The Director Ten Tors , Brigadier Piers Hankinson , met the team at the finish and presented Kingsbridge with their gold medals . The event weather , following days of heavy rain , was cloudless , sunny and warm with 100 % visibility . Notes from the Event , 2012 Manned tors . The tors used as checkpoints on the Ten Tors challenge are : This is being changed for the 2014 event . All the above tors are staffed by volunteers , ten are manned by personnel from the Royal Air Force and nine by Royal Navy colleagues . The following tors are no longer used because of bird nesting : Ten Tors Prayer . Every year before the start of the event the following prayer is read . < poem > O God who has made the Earth of great beauty , and who has given us the Spirit of Adventure , we thank you for the beauty of the world , for the courage and vigour of young people , for the companionship and for the opportunity to enjoy all these gifts . We pray that you will keep them safe on this great venture and grant that they may meet each challenge and difficulty with unselfish courage and so find the true spirit of comradeship as shown to us by Jesus Christ , our Lord . Amen < / poem > Jubilee Challenge . Since 1977 the event had also paid host to the Jubilee Challenge , which is a shorter version of ten tors for competitors who are impaired in some way ( be that a severe learning difficulty or physically disabled ) thus showing that any one can take up the challenge . The Jubilee challenge takes place on the Saturday , over distances of 7 . 5 , 8 . 5 , 11 , and 15 miles .
