The 18-year-old, from Hackney and a member of the North Derbyshire Running Club, won the Under-20s category of the British Standard Distance Duathlon Championships and is to represent Great Britain in the 2016 European Triathlon Championships in the same age bracket.
Tasmin says: "Having just started my first year at Loughborough University, studying Materials Engineering, my training has experienced a lot of change.
"I am now partaking in structured training sessions with a quality group of athletes. My main goal for 2016 is to grab the gold medal at the European Age Group Duathlon Championships in April in Germany.
"I also hope to qualify for the World Duathlon Championships in Spain, where I will be looking to improve on my seventh place from 2014
"In addition, to the run-bike-run event of duathlon, I have also already qualified for the European Triathlon Champs in Lisbon. However with the inclusion of the swim - my weakest discipline - my aim is to purely medal here.
"2016 will be my first full season of competing in the standard distance events, I feel these suit me best, so it will be interesting what results I can gain while purely focussing my training on the longer distance.
"A standard distance duathlon consists of a 10km run, 40km bike and a 5km run, while a standard distance triathlon is a 1.5km swim, 40km bike and a 10km run."
