Fortunately, Beamish was able to recover and finished second in the heat.
He then went on to stun the field in the final, beating hot favourite and two-time Olympic champion Soufiane El Bakkali of Morocco to claim gold.
Beamish won the 1500m gold at the 2024 World Indoor Championships in Glasgow.
The other two finalists for the World Athletics Photograph of the Year show America’s Noah Lyles and Tara Davis-Woodhall celebrating their respective titles at the World Champs and a photo of the shadows of the Dream Mile at the Bislet Games in Norway.
The three finalists were selected from 141 images submitted from photographers from 41 countries.
