While consistently posting strong results on the World Cup scene, the German has suffered nightmarish Olympic Games on two occasions - first in 2008 and then earlier this year in London.
Four years ago in Beijing, his horse Coster tested positive during a doping control and Ahlmann was forced to pull out of the showjumping final in Hong Kong. He had previously been crowned double European champion with the horse in 2003.
The Court of Arbitration for Sport imposed an eight-month ban on the rider in April 2009, and the German Federation did not select him for Nations Cups or championships for two years.
Yet the same year would also provide a route to salvation, as his girlfriend gave him a horse that he would develop a successful relationship with: Taloubet Z.
Atop Taloubet Z, Ahlmann won the 2011 World Cup final in Leipzig before winning the World Cup Grand Prix in early 2012 in the same Austrian city.
The pair started the 2012 outdoor season in promising fashion and Ahlmann secured his qualification for the London Olympics as part of the German national team.
But again, on the biggest stage, disaster struck and the pair were eliminated in the first qualifier while the German team could only manage an 11th place finish.
Yet Ahlmann remains undeterred; the 37-year-old certainly appears to know that the only way to get over failure is to bounce back quickly.
