Norfolk triathlete Daniel Alldis says he has taken confidence from his first attempt at the half-Ironman distance.
Alldis, 20, was the youngest UK participant at the Ironman 70.3 event in Antwerp on Sunday, where he finished 40th in the under-30 age group.
The Diss competitor told BBC Radio Norfolk: "There was lots to take away from it.
"I was around half-way up my age group which is promising. I am now thinking ahead to next year."
Alldis clocked a time of six hours, 27 minutes and 41 seconds, while local favourite Bart Aernouts won the senior male class with a time of 3:45:37.
Despite having trained for the past 10 months in order to attempt the 70.3 mile distance Alldis, who has been competing in regular triathlons since 2008, found the course a tough test.
"I suffered a lot on the bike leg," he explained.
"Cramp and huge head-winds of up to 35mph really hit me hard, but I had a fairly good swim and run which I was happy with.
He added: "I would do it again yes. I'd train harder, push harder and expect more from myself, but I am extremely pleased with my first event considering the conditions."
The race was overshadowed by the death of Belgian competitor Arthur Aghajanyan who suffered a head trauma following a crash on the cycling stage.
