    Did the event in 2019

    Worst event in terms of organisation that we’ve ever been to. Tried to fit far too many disciplines in one start area. The atmosphere was ruined by the clear stress and confusion amongst the event staff where no one seemed to know what they were doing. There was not enough places to rack bikes, not enough toilets, not enough finisher medals, not enough parking spaces. Everything seemed to go wrong! To top it off my partner and I both placed in the top 3 of our race categories, however the female names were not even acknowledged or read out. When questioned they said it’s because there were not enough trophies!
    Very disappointing and definitely not doing an F3 event again. This was felt by many people on the day.
  • Did the event in 2019

    this is a really great event. My first 70.3 and definitely not my last. Nice and varied course, some challenging hills on the bike course, and a fun atmosphere at the finish line.
  • Did the event in 2019

    Great race and fantastic atmosphere. Particularly enjoyed the hectic swim start and running down the tow paths.
  • Did the event in 2015

    Excellent event on the River Thames and very well organised. The river swim leads to a great start to the day although be warned that the temperatures can be a little chilly! This is one of my favourite events on the calendar and leads to great weekend on the outskirts of London.
  • Did the event in 2014

    It was my first half Ironman but I was made to feel at ease with a lot of other competitors who were competing at this distance for their first time. The organisation was smooth and the course was along the river. The surrounding areas is lovely to visit pre and post race as well.
  • Did the event in 2019

    well organised race and good course. Would have been nice to have done a couple more aid stations on the run.
  • Did the event in 2019

    Organization was general good, course signage, marshalling etc. However, after a warm-up run, I turned up at the start at 08:25 ready for the advertised 08:30 start time only to find the race had started 10 minutes early and everyone had departed. The senior marshall was apologetic and took a note of my revised start time and said they'd adjust my time. Just took a look at the results and, of course, no sign of any adjustment. Not impressed.
  • Did the Triathlon - Standard in 2019

    Great event with a lovely river swim and a run along the river path. Slightly delayed start but didn't affect the day!
  • Did the Triathlon - Standard in 2019

    Lovely course and great event with a super atmosphere. All the event volunteers were very friendly and helpful. Real pain in the proverbial to have to come the day before to register, not to mention the climate impact of everyone doing the round trip twice. Timing on the day was a bit off, race started 15 mins late and the start of the swim was rushed with the start going about 5 seconds after the last person got in the water.
  • Did the event in 2014

    This was my first ever 70.3 distance and I absolutely loved it. Hectic start in the water with all starting at the same time - my timing chip was actually pulled off me and I had to get a new one - but this added to the fun. Great atmosphere in the athlete village and it was a lovely touch being handed a beer at the finish line!
