TROWBRIDGE teenager Sarah Wilson delivered a winning performance at the National Tetrathlon event at the University of Bath.

Having only recently returned from the world championships in Portugal, Wilson took part in the U19 age group and was 10th after the 50m swim.

In the fencing salle, she scored a credible 12 victories to eight defeats, which moved her up to sixth and the handicap system of the laser run saw her start 39 seconds behind first place.

Despite her shooting being off par, strong running saw her overtake the field and claim the gold medal for the third time this year.
