Mark English broke the Irish 800-metre record on Tuesday night, and secured Olympic qualification in the process.
The Donegal athlete clocked a time of 1-minute 44-point-7-1 seconds while placing second behind Yassine Hethat in Spain.
English shaved just over a tenth of a second off the previous Irish best of David Matthews, whose record lasted 26 years.
His qualification time for Tokyo came just hours before the deadline.
