In the early 1900s he emigrated to Australia and by 1907 was living in Newcastle, New South Wales, by which time reports indicate that 'he had been working in various jobs and locations for several years'.
[5] At the outbreak of World War I he was resident at 3 Adeline Street, Preston, a suburb of Melbourne, Victoria, when he enlisted in the Australian 21st Battalion.
This was his first attempt at a distance greater than 10 miles on a cinder track and he easily broke the 59 mins 1.6 secs record set by Schaeffer.
The following day at the Vailsburg, Newark (New Jersey) cycle track he beat John Bedell in the half-mile handicap for professionals but was then scheduled, without recovery time, to immediately contest an 'Australian Pursuit' race against W.S.
Setting his head in his own peculiar style on one side, partly over the front wheel, with grim determination and speedy pedalling he never fails to bring the field back to him.
Despite an initial lack of fitness, Gascoyne's natural speed meant that he was soon relegated to 'scratch' in the handicap races at night carnivals.
Eventually rumours spread and the two riders had to reveal their true identities but their integrity remained intact, they had simply retired from racing to concentrate on manual labour careers.
[15] In December 1912 he declined an invitation to enter the Sydney 6 Day Race with his old partner Sidney Jenkins, because he ...cannot leave Melbourne without forfeiting a good position, which [he was] not disposed to do.
[16] Corporal Thomas Jepson Gascoyne is listed at the Menin Gate Ypres as having died on 4 October 1917 in the Battle of Broodseinde in World War I.
