Any old Ironman

 

Sir, – Brian O’Connor wondered what half an Ironman should be called in the same paragraph in which he mentioned the periodic table (Tipping Point, Sport, August 27th).

Surely the best name for half an Ironman should be an Aluminium Man given that the atomic number of aluminium at 13 is half that of iron. – Yours, etc,
