This part weekend I competed in the Blenheim Palace Triathlon, a sprint distance event set in the grounds of the beautiful Blenheim Palace on Oxfordshire. The event was great and incredibly well organised and I thoroughly enjoyed my first open water swim triathlon.
The Event
This was a sprint distance triathlon, consisting of 750m lake swim, 19.8km bike ride and a 5.4km run. The even took place over both days of the weekend, with me competing on the Sunday. It was primarily a sprint distance event, although there were a few super-sprint waves plus a couple of corporate relay waves as well. Got lucky with the weather, as by the time I started on the Sunday lunchtime the drizzle had disappeared and the bike course had mostly dried out.
My Performance
I was very happy with my performance, finishing the event in 1:23:36, which was just a fraction quicker than my target time of 1:25:00. Finished in 192nd position out of just over 4200 starters, and 36th place in the M40-44 age group. There were 78 competitors in my wave, from which I finished in 3rd place. Breakdown of the time was:
| Event | Time | Position Overall | Position in Wave |
|---|---|---|---|
| Swim | 15:48 | 770th | 15th |
| T1 | 04:06 | 205th | 1st |
| Bike | 39:07 | 457th | 9th |
| T2 | 01:21 | 53rd | 2nd |
| Run | 23:17 | 118th | 1st |

The Swim
This was my first ever open water swimming event. Prior to the race I'd done four other open water swims in the local training lake, but if was safe to say this was the part of the day that I was looking forward to the least.
The lake start is a 5-10 minute walk downhill from transition, so make sure you leave in plenty of time. It's also a path with a few stones, so if you have supporters it's worth walking down in flip-flops and getting them to bring them back up. The assembly point was pretty friendly and we collected our wave coloured swim caps . The safety briefing was excellent and ended with a hug with the person next to us. Then it was in to the water and a short swim out to the deep water start.
The lake at Blenheim is fairly deep and you can't see the bottom, so not one for very nervous swimmers. I'd reached a point in training where I knew I was comfortable with the distance, so it was just a case of dealing with the mass start and keeping my breathing under control. The horn sounded and we were off.
The first 300m was horrible! Even though I'd tried to position myself to keep out of the melee, I found myself surrounded by jostling people. People bashing in to me, hitting my legs, cutting across in front so that I hit them. It was almost impossible to get into a good swimming rhythm, my breathing was all over the place and a building sense of panic started to come over me.
I focused hard on keeping my breathing smooth and trying to relax. Then, the field started to spread out a bit and I found some smoother water and clear space. I was then able to get into a good stroke and breathing rhythm and everything settled down nicely. Managed to turn nice and tight to the buoy and even started overtaking some other swimmers during the closing stages.
Then I was at the slip ramp, out of the water, through the shower and heading up the hill towards transition. I didn't think of looking back to see how many people were still in the water, but I imagined that I was a good way down the field at this point (when actually I was 15th out of the water).
The swim part of the event can be seen below. My watch measured it at 870m, but that includes a bit of the run at the end and the fact that my line wasn't perfectly straight due to dealing with other swimmers and my inability to swim straight!
T1
The run from the lake back to transition is 400m, all uphill on a coarse carpet. I was out of the top part of my wetsuit by half way and taking care to try and stop my heart rate spiking too high. Looking at the stats I was fairly successful as it reached 179 just after exiting the water and I had it back to below 170 by the time I reached my bike.
It was at this point I realised I'd actually had quite a good swim as there were very few people in our rack lane of transition.
I'd laid out my kit carefully and it paid off. Wetsuit slid off easily (glad I'd practiced that in the back garden the day before!). Number belt and socks went on quickly as did bike hat and sun glasses. Pushed the bike out and did a smooth mount, including getting into my pre-clipped shoes with no drama.
I was the 205th fastest of the whole event through T1 and the fastest in my wave. Probably the only way I can significantly improve on this stage is to drop the socks and bike and run in just shoes. I'll definitely be testing this out before my next event in September.
One other word of note is that transition is carpeted, but the carpet appears to have been laid over a stone/gravel courtyard. You can feel the stones right through the carpet! I have bruises on the bottom of my feet from standing on these stones during transition. No way to avoid it, but something to be prepared for.
The Bike
I've been working hard on my bike and I think this had a real impact on my bike leg performance. I felt strong throughout the bike leg and the three laps seemed to pass by in a flash. The bike course at Blenheim is pretty undulating, with one longish (1km) steep up-hill (5-11%) and a couple of nice down-hills, including 2km at about 2-3% gradient. Felt strong on the up-hills and took the down-hills pretty fast. Perhaps slightly too tentative on the first lap, but attacked the hills more on laps 2 and 3. Strava estimates my average power at 211w, which is significantly higher than I usually achieve on training rides.
The only complaint I have over the bike course is other riders. Unfortunately the two waves prior to ours were corporate relay waves and thus, by the time I reached the bike, the course was still full of riders travelling significantly slower than I was. On the up hills there were lots of people wobbling all over the place at walking pace, which made overtaking on the fairly narrow paths a somewhat risky endeavour. Then on the down-hills there were lots of people travelling a bit slower than me but still making various overtaking manoeuvres on a number of very tentative riders. I therefore had to hold back slightly in a few places more out of safety concerns for myself and other riders.
I think the marshals could have done a better job of ensuring that slower riders kept well to the left to leave enough space for overtaking. There were some places where I had to brake on a downhill in order to avoid the drafting zone of the bike in front as there was just no space to overtake safely with riders already 2 or 3 abreast. The top bike times from our wave were all slower than most other waves and I think this was largely down to the volume of other riders littering the course.
I also found it quite disconcerting that in a few places there were marshals positioned with white flags yelling at everyone to slow down. I understand this is for safety, due to tight bends or bumpy roads, but after the first lap I felt my awareness of the course was good enough to be able to take these at speed and in full control. However I still felt obliged to back off slightly with the marshals shouting 'Slow Down' at you repeatedly!
Given a clearer course and the fact that I now know all the bumps, turns and hills, I think I could probably shave another minute or so off the bike leg if I attempted it again.
T2
I managed a smooth dismount from the bike, including taking my feet out of my shoes on the final straight with no incident. Quickly back to the bike stand, although I did loose a couple of seconds trying to spot my kit position on the rack, even though I'd mentally marked it's location in line with the advertising hoarding logos. Hat off and into running shoes. Then off again. I was 53rd fastest in the whole event in T2 and second fastest in my wave.
Took the gel that I'd attached to my bike but didn't need so I could fuel up early in the run. A great transition and probably still have a few seconds I could shave off as well in the future.
The Run
The run was always likely to be my strongest discipline and it turned out to be true. I felt really strong through the run and managed to complete this part in the 118th fastest time of the day, and 1st in my wave: more than twenty seconds faster than the next best.
I probably could have pushed a fraction harder in the first lap of the run, but a cracking second lap averaging 4:00/km on a very undulating course made for a strong finish. Lots of overtaking runners from the earlier corporate waves also gave the feeling of moving very fast!
One thing I did find very different was the fact that by this stage in the event everyone is very spaced out, including runners from multiple waves on the same 2-lap course. I was therefore running largely alone without knowing where I was relative to other racers in my wave. This is a very different sensation to a mass start run where you are constantly striving to catch the runner just ahead of you, knowing that each person you overtake is an improved place in the final results.
Crossed the line with a big smile and picked up my medal, bottle of water and a glass of Erdinger Alkoholfrei isotonic beer (I'm a non-drinker and don't really like beer, but this tasted okay – however that might just be because I was really thirsty at this point!).
Atmosphere and Organisation
For such a large event, I'd have to say that the organisation was immaculate. Everything ran pretty much like clockwork. Pre-race packs arrived early and the race guide had everything you needed to know clearly spelled out. Parking was well organised and timing chip collection very smooth
Racking bikes in transition was very well managed. All the instructions were really well presented and the announcements in transition and the swim start were clear and precise. The pre-race briefing was superb. All the marshals did a great job and offered clear instructions and direction, although those on the bike course could have done a slightly better job keeping slow riders to the left of the paths.
With such a big event you always get a great atmosphere and there was plenty of cheering on the way up from the swim and around the main straight in front of the palace building. Race village was good and there were plenty of toilets and lots of good food options.
Conclusions
I had a really enjoyable day, got a great time, conquered the mass-start open water swim that I was really nervous about and put in a very strong bike leg. The event was really well organised, if a bit expensive to enter. I'd certainly recommend it as a great location for a first sprint triathlon.
I'd certainly consider going back again next year, but I'm also keen to step up to standard (olympic) distance events and Blenheim Palace doesn't offer this distance as an option. I'd therefore be doing it as more of a training race, and it's probably a bit too expensive to enter on this basis.
Now going to take it easy for a few weeks, keep up the open water swimming and start thinking about training for my local pool based sprint triathlon at the start of September.
