Both siblings have played competitive tennis as juniors with Ewen progressing to the senior level. Educated at Beaconhurst School, Bridge of Allan later studying at nearby University of Stirling after returning to Scotland in 2016.
Recognized as young as ten years old as the best in Britain in her age group and training at the national academy, University of Stirling, under coach Toby Smith with mentoring by Judy Murray who said at the time that Lumsden may need to train abroad to realise her potential.
By 2012 she was the No. 1 under-14 player in the Tennis Europe rankings and under-14 champion at the Junior Orange Bowl beating Gabriella Taylor 6-3, 7-5, in an all-British final. The following year the two players teamed up to become under-16 British National Junior Champions in the Doubles whilst Lumsden was also the under-16 Singles Champion.
Gabi Taylor, Katie Swan, Freya Christie and Lumsden were members of the 2014 British team, coached by Judy Murray, that triumphed in the Maureen Connolly Challenge Trophy, an annual Under-18s competition against the USA.
As a 14 year old, she won her first matches at Challenger level beating England's Pippa Horn and Oman's Fatma Al Nabhani, the second seed and world No. 463, to qualify for the AEGON Pro Series event at Scotstoun.
Lumsden's first full year as a professional saw two individual title wins in Sunderland and the Wirral and six ITF Futures doubles finals, three of them as winner.
Entering her home competition in Scotstoun as a wild card, Lumsden lost to her Spanish opponent Paula Badosa Gibert in the final of the GB Pro Series or Scottish Championships. In November, Lumsden claimed her first 25k title, beating former top 100 player Valeria Savinykh in the final.
In February, Lumsden lost at the quarterfinal stage in the W60 Shrewsbury tournament to top seed Yanina Wickmayer. She made her WTA Tour debut at the Nottingham Open in June, after receiving a wild card to the main draw of the tournament, winning her first match against fellow Brit Tara Moore, before losing the following day to top seed Caroline Garcia.
