Get ready for the Marlow Half Marathon, Marlow 7 and The Frankenstein on Sunday, 5 November 2023.

This year we have exciting news – it is the 35th running of the Marlow Half Marathon and we are also launching a new race “The Frankenstein” – a multi-terrain event, approximately 10km, one third on road and two thirds on trails – named in honour of Mary Shelley's novel "Frankenstein" which she completed whilst living in Marlow. We will also be running the ever-popular Marlow 7.

The following elements are included in 2023 (subject to change):

  • Race bib (with integrated timing chip). This will be allocated to you at the registration desk.
  • Electronic timing and online live results
  • Race village – with food, drink and merchandise stalls
  • Music at the start and finish
  • Baggage drop
  • High-quality long-sleeved T-shirts to purchase* (whilst stocks last)
  • Race medal
  • Awards ceremony
  • Downloadable finisher certificate
  • Pre and post event massage (available to pre-order for a discount)
  • Drink stations on course and at the finish
  • Post race snacks at the finish line
  • Medical provision at start, finish and on course
  • Course safety – signposted mile markers and enthusiastic marshals
  • Toilets at Race HQ


*To minimise the environmental impact of this year's event, we are not including a T-shirt as standard, thus enabling us to significantly reduce our race entry fee.

Recognising that many of our runners would like a T-Shirt, we do have high-quality, long-sleeved technical T-shirts to purchase featuring a 2023 design to commemorate the 35th anniversary of the Marlow Half Marathon and the inaugural Frankenstein. They are perfect for running in cooler temperatures! You can choose between a female or unisex/male fit and a range of sizes. Click here to view this year's T-Shirt design and sizing charts.
