The 20-year-old, who pulled out of Sunday’s javelin event because of a sore elbow, threw 46.96 metres, just short of her PB of 47.26m, which she achieved in September.
‘What people have to remember is that for a lot of us this is not even the start to our season and we have had to train all the way through winter,’ said Thérin moments after the event.
The former Grainville pupil revealed that it was her first competition throw since setting her PB in the autumn.
‘I knew I was never going to make it through to the last eight, but I thought I would give it my best shot and that’s what I did.
‘Each throw I was taking was going further and further and I think that if I had one more throw I would have thrown a PB.
‘This is a great arena and very noisy, but I soon relaxed and started enjoying myself.’ Thérin threw 44.21m, 45.56m and then 46.96m in her final throw.
This placed her 14th out of the 14 competitors.
‘I know it’s a lot for Jersey to bring me out here and I hope the squad aren’t disappointed with me finishing last.’
