How do I get to Blenheim Palace?  

Blenheim Palace, Woodstock, Oxfordshire OX20 1UL  

Blenheim Palace is situated in the Woodstock, 8 miles north west of Oxford on the A44 Evesham Road and approximately a one hour drive from the outskirts of both London and Birmingham.  



Approaching Oxford on the M40, exit at junction 9 and follow signs to Blenheim. From other directions take the A44 exit from the Oxford by-pass.  



The nearest British Rail main line station is New Oxford Parkway. The S3 bus runs from Oxford to Woodstock at approximately 30 minute intervals. There are car parking facilities for cars and coaches and car parking is free for competitors.  


What time do I need to arrive?  

In order to set up in transition and be ready for your race we recommend that you arrive 90 minutes before the start of your wave. You then need to be at Swim Assembly point 20 minutes before your wave is due to take place, this is to ensure you have partaken in our safety briefing and have received your swim cap  


What do I need do with the items in my event pack?  

The bib number is used for the cycle and run elements of your challenge. The number goes on your back for the cycle and on the front for the run. This can be attached with safety pins, however, it is recommended to use a race belt. You simply attach your number to the race belt and then put the clip it around your midriff. It can then be moved to show the number on your back for the bike and on the front for the run.  

The bike number stickers are placed on the front of the bike and the top of your helmet which serves two purposes.  

- To ensure you are taking the correct bike out of transition  

- You can be identified on our official photos which you may wish to purchase  

Your wristband needs to worn to get you in and out of transition. Without this you cannot gain access to this area  


Do I need a wetsuit?  

Wetsuits are compulsory for this triathlon for the safety of our participants. Your wetsuit will keep you warm and improve your swimming speed; a wetsuit provides you with extra buoyancy and the higher you are the faster you swim.  

Your wetsuit must be a neoprene and we recommend a full body wetsuit, it can be a short or surft wetsuit, however these are less useful for open water swimming. 


What do I wear underneath my wetsuit?  

Nudity is not allowed in the transition area therefore, you should ensure you wear whatever you feel comfortable in for the run and the cycle.  Most triathletes will wear a tri suit as this can be used for the swim and the cycling element of the race.  


Can I listen to a personal music player whilst racing?  

No. You will be unable to hear other competitors or the marshals when you are wearing one and consequently pose a threat to others  


How can I be sure that the water will be safe to swim in?  

We conduct numerous tests right up to the race day itself to ensure that the water is safe to swim in.  


Can I use any stroke on the swim?  

Backstroke is not allowed, as this can be confused with our distress signal. We recommend that you try to swim front crawl but breaststroke is also permitted.  


Can I use tri bars on my bike?  

Tri bars (and handlebars) must be plugged and they must be secure. There is no requirement for them to be shorter than the brake levers unlike in the elite races.  


Does my bike helmet meet safety standards?  

Your helmet will pass the safety inspection as long as it has no cracks in it, has no damage to it and bears a CE & EU safety mark inside it. The strap must also be in good working order.  


Is the race draft legal?  

Drafting is against the rules for all but the Elite Competitors. You must not take shelter cycling behind or cycle beside another competitor during the race. You can be disqualified from the race for drafting. The draft zone is a rectangle measuring ten (10) metres long by two (2) metres wide. The centre of the leading 2 metre edge is measured from the back edge of the back wheel.

Is water available during the races?  

This year, to reduce contact with volunteers, there will be no water stations offered on the route.  Water will be available once you cross the finish line. 


Can I take part if I have a physical disability?  

Unfortunately, The Blenheim Palace Triathlon is not suitable for wheelchair athletes due to the narrow paths on the run route, steep terrain to access the water and small transition entrance/exits in the Palace courtyard. The Palace itself is wheelchair accessible and we welcome spectators out to support along the route.
