Great parking
I enjoyed the run, I ran the 15k, 3 laps of the course. The half marathon was about a mile or 2 behind so many of those runners came through but it wasn't crowded.A steward helped with my parking space when spaces became available at the boathouse which saved me a walk before the start.I like dorney lake in general and this was a well organised race to take part in there.… read more
THE BAD: Race instructions were clearly pinched from the triathlon as they instructed you to bring a bike!Collecting the numbers was a bit confusing as I didn't see any signage and there was a lot of finishing off triathletes around preparing for a presentation and doing their own post race stuff so it was all a bit baffling. Not that amused that F3events website described it as a "fully licensed and certified by UK Athletics" course, but didn't make it clear it's not got a UKA/runbritain race license so won't count on Power of 10 or RunBritain. Probably wouldn't have paid the 35 entry if I'd known that - you only get a generic sort of medal for it, so I'm not sure what the entry fee goes on.THE GOODThe car parking attendants on the day were very helpful at managing a mass of cars - be aware that you might end up parked about half a mile from the meeting area though as they park along the road once. Not many runners so no getting jostled and held up along the wayHad a 1.40 pacer, which was unusual and very helpful for me.

Very nice and flat course. Not overly scenic but flat and fast so great for beginners or getting PBs. Nice and basic race

Water stations well stocked and friendly volunteersDefinitely a flat course and lots of pb potential and I quite enjoyed knowing what was coming each lap so I could judge my pace
Great flat course as advertised, with water stops and gels every 2.5km or so. Facilities before the start and after were also good, with use of boat house.
Great race for all abilities. Flat course with great support. Ive done this event several times and hope to be back for more
Expensive!!Didnt seem particularly well organised. Zero signage to help out with registration, start or finish areas. Joining instructions were useless- clearly a cut and paste from another event and course map was incorrect.Course was pretty mind numbing but that was to be expected with a 4 lap race.Not entirely sure where the 30+ entry fee went - other than to F3 events in profit.Much better organised and value for money events out there.
I chose this course as part of my training towards other events but also because of the pb potential. I completed an Olympic duathlon back in November 18 so knew that the course was relatively flat. The race briefing was a little behind schedule although clear on the course to run and instructions provided. The atmosphere was also friendly and I chatted with a few people to see what their goals were and if they had run here before. The pack for the event was mixed which is great to see a blend of experience. The race itself was very good and easy to manage your pace in line with your strategy. I predominantly run trail events so it was a change for me to run multi laps on flat tarmac. Once set in, it is mainly 4 laps (not always great completing laps as there isnt much to see but that is not why i entered)so you chalk them off as you go, knowing that once lap 2 is out the way you are over half way round. My goal was to have a new pb and beat 1:32:44 so I was aiming for 1:30. Conditions were great on the day, not hot a and very little breeze. I finished on 1:29.04 so very happy. It is worth noting that the straight back to the boathouse is a little deceiving and felt very slightly uphill. Would I compete here again, yes I would. Very well organised as there were many events on the day and friendly competitors/marshalls alike.
The event was very well set up and registration was very straightforward.Nice course, flat and scenic. I think it would be a beautiful run in the summer as it was a bit grey and chilly. But enjoyable none the less
A no-nonsense extremely flat course, ideal for getting a HM PB (which I did -7mins). Really well organised and very close parking. Would thoroughly recommend this course.
Event was very well organised, the course was accurately measured and pretty flat. There was water and gels on the course and the results were available immediately afterwards.Would definitely run it again.
Course was OK but a bit boring as its juat 4 laps of a lake. Not the best organisation either leaving was a bit chaotic du to lack of people directing you. Also no way of getting your chipped time on line so I have no idea what it was. Just have to go by my own watch time.
Great racing at the wonderful Dorney Lake. A quick and flat course that's an ideal setting for PBs.
There was no bike mount line.Loving the trophies, keep those coming.
Really well organised - fun atmosphere & clear for a first time duathlon
The course experience benefits from good weather and for this race it was excellent. Bright winter sunshine and little wind. Really suits a TT bike and would have been good to have more competitors, but its early in the season. I would have liked to know how I faired in my age group though, being 23 years into the V40 group left me somewhat towards the back!!
Good race, would say that if I was to do it again I would do the first 3 laps same speed but would do the last lap quicker.
More toilets!! Only got offered an energy gel once in the 4 laps and a second energy gel would of been nice!
well organised, a couple of points, due to the narrow roads on the return leg it was often difficult to pass people, maybe asking people to keep left would help. additionally, some cones or something similar might be appreciated on the exit of t1 as there were a few tight moments with people moving onto their next lap :)
Good race with great atmosphere, highly recommended for those who are getting into duathlon world.
The weather at Dorney is usually either cold or windy, sometimes both. Wrap up warm and be prepared for crosswinds on the bike.
Get there early - long line for registration and limited toilet facilities etc.
Brilliant course very simple to navigate and very flat perfect for PB running (which I did) my only comment would be that the course markers were confusing and for relatively inexperienced runners like me that do not have all the gadgets to track your progress, the distance markers were confusing!
The registration was slow and you could only get there an hour before the start of the race so that didn't help. There were only 7 porta loos which were not enough for the amount of people. It was pretty stressful for me as I got to the venue late and by the time I had queued for the registration and a visit to the toilet, all the runners had started and gone which left me on my own until I caught up with them! It was my first time at Dorney Lake so I didn't really know the layout of the course and had it not been a handful of marshalls, I would of gotten lost as the signs weren't clear. However, this was only the first lap after that it was just 3 of the same laps which I did find monotonous!
Get there early, there were only I think 6 toilets and a long wait, the course is flat but the wind can make the middle section cold and exposed, water and gels were available and there was a Costa van.
Really lovely sunny day made my first Duathlon considerably better than I expected. Simple running route & bike course helped me get through it. It felt a bit rushed between registration and getting the bike ready for transition but all just part of learning what you need for your first one.
