As well as testing conditions during and after the monsoon, the expedition was to test likely climbers for 1936 and follow up the exploratory work of the
1921 reconnaissance. Explicitly there was to be no summit attempt and supplementary oxygen was not going to be used. Tilman initially regretted having to abandon the Nanda Devi summit attempt but Shipton persuaded him by the lightweight exploratory nature of what was being planned. Charles Warren and
Edmund Wigram, both Cambridge medics,
Edwin Kempson a Cambridge mathematician, and
Dan Bryant, an ice climber from New Zealand agreed to take part. Shipton considered this complement quite ample but he found he had a surveyor,
Michael Spender added to the team. Spender had made himself extremely unpopular on earlier expeditions due to his conceit and there were rumours that his inclusion was due to mischief making. All the same, Shipton and Spender became close friends. Shipton deplored the extravagant lifestyle practised by the earlier British expeditions. He consulted a nutritionist at the
Lister Institute to determine an efficient diet producing 4000
Calories a day in conjunction with locally sourced food. Lentils, dried vegetables and powdered milk were on the menu with the addition of
cod liver oil along with
ascorbic acid and
ferrous sulphate tablets. This contrasted with the caviare, foie gras, quails' eggs and lobster of 1933 and even Shipton later admitted "In 1935 I went rather too far the other way: it was bad policy to force people who were quite unused to rough food to make such a complete break with their normal diet." The team members reached India and met at
Darjeeling on 21 May 1935. With the help of
Karma Paul, who had been on all the Everest expeditions since 1922, they engaged fourteen Sherpas but Shipton decided he needed perhaps a couple more and a nineteen-year-old was selected. He was completely inexperienced in mountaineering but was chosen according to Shipton largely because of his attractive grin –
Tenzing Norgay. The party headed north through
Sikkim into
Tibet and then travelled west towards Everest on a route through
Sar – further south and nearer to Nepal than earlier expeditions had used. When they reached the
Nyonno Ri () and Ama Drime () mountains they split into three groups for exploration. This had all been contrary to the stipulations in their passports issued by Tibet and they were ordered back north through
Gyankar Nangpar and onto the traditional road. Earlier from Nyonno Ri they had had a fine view of Everest in unusually good weather conditions and it has since been speculated that, had they made a dash for the summit, they might have succeeded. However, Shipton made no such bid, and indeed it was forbidden by his passport and by the remit of the expedition. They reached
Rongbuk Monastery on 4 July. == North Col ==
