KATHERINE ENDACOTT will be testing her self-belief and hoping the hours of practice pay off at the UK Indoor Athletics Championships and World Trials in Sheffield this weekend.

City sprinter Endacott is chasing down a 60m slot at next month's Indoor World Athletics Championships in Turkey at the English Institute of Sport, which she hopes will end a frustrating campaign on a positive note.

The double Commonwealth Games medallist knows she will have to post a career best personal time of 7.3secs in order to qualify for the Istanbul event from March 9-11.

That Endacott is 'busting a gut' to compete at all is testament to her conviction in her own ability and determination after a wrist injury put paid to most of last year's outdoor campaign and delayed her indoor ambitions this winter.

The 32-year-old has had just two indoor meets, at a Cardiff Grand Prix before Christmas and last weekend at the Birmingham Indoor Games.

She won easily at the University of Cardiff in Wales event and returned from Birmingham with a silver medal in the 200m, but also a frustrating fifth in the 60m final after impressing in the heats and semi-final in the shorter sprint event.

Endacott, who is also a member of Team GB's bobsleigh squad, has her sights set on this year's Olympics, where she hopes to win either a 100m relay place or better yet an individual slot.

The indoor season was supposed to give her competitive edge and preparation, but now that she scents an outside chance of doing both London and Istanbul, Endacott has been working hard with her dad, Steve, City of Plymouth athletics club's sprints coach.

Sensing she is not far away from a late qualification spot, Endacott's dander is well and truly up for the Sheffield shoot-out.

Endacott told Herald Sport: "I'm annoyed with myself rather than disappointed in the 60m at the Birmingham Games, so I'm going to have another go in Sheffield.

"I won my heat in 7.63 secs and was third in the semi-final (7.65) but finished fifth in the final (7.69).

"I was really angry with myself and that I hadn't myself justice.

"For example, I was happy with two-thirds in the 60s – my start and then the drive – but the final 20m I was tensing up and couldn't change up a gear.

"But that's just technical fine tuning and given that it (Birmingham) was my first really competitive 60m for around 10 months, I should be pretty satisfied.

"But I'm damn well not, as I know that I can run faster and it's that sense of a job unfinished which gives me hope of making up for lost time."

If Endacott was disappointed with the 60m she was a lot more upbeat at her 200m time and medal.

She said: "With the 200m, I could be overly critical and say that I need to learn how to run bends again indoors and that in lane six I was basically the hare for the others.

"But, I came second in 24.51 and went through the semi in a good time, too, so again it shows there's more to come.

"At the UK Champs and World trials I will probably concentrate on the 200m, but the 60 is definitely another option."
