From the organiser

This is the 10th year of the Marlow Sprint & Olympic Distance Triathlon, consisting of a river swim, cycling and running. The event has attracted 1000s of participants over the year and is open to all levels of participant and encourages first time triathletes to the event.

The Swim course is in the River Thames. It is designed to make even the weakest swimmer get a fast swim split.

The Marlow Classic Half Iron Distance is the only long distance event in the Thames Valley and is a fairly flat scenic course taking in the views of Marlow and the surrounding areas.

The Bike course for the Sprint Distance is 24.5km & the Olympic Distance is 37km. It is an out and back course and only has two hills, but otherwise fast and flat.

The Run course for the Sprint Distance is a 1 Lap 5km route & the Olympic Distance is 2 Laps for a 10km. The course is on Tarmac and Grass Footpaths. It meanders back towards Marlow and into the finish at Higginson Park from the river tow path.

The event is set to attract over 700 participants, as the world of endurance sports and triathlon creates massive demand for longer distance events over the shorter distances that have originally formed this great sport.

  • Did the Olympic in 2018

    1:The day was great however having to go and pick your pack up the day before was a pain......2:The biggest thing for me was the colour of the buoys in the water, they should of been yellow, red, or orange and not blue/purple as they were very hard to see while you are swimming!!!3:The water stations were very close together which didn't make much sense cold of done with one more water station.

    I had to make a extra trip to Marlow to pick up my race number. It could have been sent in the post and it seems it was possible to pick it up on the day. It was an hour round trip.
  • Did the Sprint in 2018

    Good race, well marked. People were drafting though and marshals didn't know the rules so cheating was going on but overall was good.
