Baulch made his debut for the GB & NI team at a Junior International in Salamanca, Spain, in 1991, winning the 200m and breaking the Welsh record in that race.

In 1993 Baulch ran a Welsh record 46.50 at Sheffield in his first individual race at the distance since 1990,[citation needed] and he made a breakthrough in 1995 when he progressed to 45.14.

[1] Baulch received his World Championship gold medal in May 2010 and, although he was happy, he said: "It would have been great to have been in front of 80,000 people up on the rostrum...nothing can replace that.

Later he made the World final outdoors with a season's best 44.69 in the semis and ran a 44.08 third leg on the British silver-medal relay team.

[citation needed] Baulch was selected as captain of the British team at the 2001 World Indoors, but had to withdraw through injury and struggled for form in the summer, with a season's best of 46.15 in the heats at Edmonton, where he ran an encouraging 44.4 second leg for the British team in the final of the World 4 × 400 m. With an individual best of 46.01, he was again seen to best effect in relays in 2002, with a third leg of 45.1 to help Britain to victory in the European Cup 4 × 400 m and a third leg of 44.5 for the Welsh team that took the silver medal at the Commonwealth Games in a race against England.

[citation needed] Baulch also became a squad member for the Welsh touch rugby team in 2010 which won the European cup later that year.

[citation needed] Baulch excelled as a trampolinist in his youth, and won a silver medal at the Welsh Schools Trampoline Championship in 1991.
