I know someone who did it this year - they said it was a great experience. he did say that good weather helped! it's a very flat course which will appeal to many - and perhaps why it sells out quickly! he did get a PB as well which helped his experience
one thing he did say is that it's not easy to get to! he drove over in his motorhome - 3 days to get there, 3 days to get back (the trip was part of a longer holiday)
there are other good Euro IM that are easier to get into and easier to get to - Wales, Switzerland, Germany etc - that many of us have done
