title: Biochemical observations on a non-elite marathon runner.
abstract: Biochemical observations made on a 30 year old male marathon runner before, during and following the race are described. The prolonged exercise appears to result in gluconeogenesis using non-essential amino acids as substrates while essential amino acids except lysine are spared.
