The outrageously gifted German Niklas Kaul will start favourite to claim the inaugural boys' decathlon title at the IAAF World Youth Championships.
Previously the boys' combined events competition has been run as an eight-event octathlon, but Kaul will be the man to beat in Cali after accruing a 10-event haul of 7783 points in Filderstadt to climb to second on the world youth all-time list.
Kaul is also the world No.1 youth athlete in the javelin.
He will face strong Estonian opposition in the shape of Hans-Christian Hausenberg whose 7713 points elevated him to fith on the world youth all-time list and Martin Moldau.
The last ever world youth octathlon champion Karsten Warholm hailed from Norway and his countryman Toralv Opsal (7444) will aim to maintain their combined events tradition in Cali.
Kaul’s compatriot Maximilian Vollmer (7407) and USA’s George Patrick (7282) could also feature in the medal hunt.
