He reportedly suffered a calf injury during the competition, but still managed to achieve a distance of 19.75 meter, with which he fell just 4 centimetres short of the place in the final, which ironically went to his compatriot Janus Robberts, though Canada's Bradley Snyder was even closer with 19.77 metres.

[7] In February 2001 Lambrechts established a new South African record with 20.90 metres in Port Elizabeth, but the result was later disqualified as he was found to have been using the anabolic steroid Stanozolol.

He'd tested positive for the substance at the meet in Port Elizabeth and also in a control seven days later, and was subsequently banned from sports for two years by the Athletics South Africa.

The same month he achieved a lifetime best throw of 20.63 metres in Pretoria, which ranks him second in Africa behind fellow South African Janus Robberts.

In 2007, at a bodyweight of 135 kg, Lambrechts became the heaviest person ever to successfully complete[11] the 250 kilometer Kalahari Augrabies Extreme Marathon, an event billed as the toughest footrace in the world.

He competed at the World Indoor Championships in Istanbul, Turkey, but injured his middle finger the day before the competition in training (he fell on his hand and chipped the bone), causing him to only reach 18.96m and end 17th.

During the early stages of 2013 Lambrechts suffered from a foot injury, preventing him from entering any competitions, but in August he competed in the World Highland Games in Glasgow, Scotland.
