Dear General Secretaries,

It is with great pleasure that we attach the General Information Sheet for the IAU 100 km World Championships in Ames, Spain on 20^th September 2026.  This provides you with all the information on the site of the championships, travel and accommodation details as well as the entry procedure.  Federations are reminded that this year there will be no travel grant for federations and this information was published on the IAU website recently,

This year we will be using the World Athletics Event Entry System with thanks to World Athletics for its use.  

Federations will be familiar with its use for World Athletics Championships and for the World Mountain and Trail Running Championships for the last years.  IAU Federations that do not have access via their WA Federations are encouraged to liaise with their colleagues or if necessary contact us below.  

Access to the system for the Preliminary entries will be on 1^st June and will close on 30^th June and the Final Entries can be supplied from August 1^st  until the final deadline of 30^th August.  

Please contact us if you have any queries and looking forward to seeing your teams in September in Spain.

Hilary Walker

IAU General Secretary
