The Watermelon Sandglass Ultra is a Last Man Standing event with a twist. Every lap you lose a minute from the cutoff. On the first lap you have 60 minutes to complete the 6.3 km out and back. The following lap you will only have 59 minutes to do so. This will continue until there is only one person capable of completing the 6.3 km lap.

Race course is in Bukit Nanas Forest Reserve and areas around it, where this ecological haven was first established as a reserve in 1906, rendering it one of the nation’s oldest conservation areas. Set in the heart of Kuala Lumpur’s bustling city centre, one can now discover the enchanting KL Forest Eco Park, a verdant oasis concealed amidst an urban sprawl. In addition to its strategic location and proximity to the city centre, KL Forest Eco Park also offers a variety of activities and attractions catering to visitors of all ages.

Each lap will have roughly 170m of elevation gain and loss. There will be one aid station at the start/finish area.

This is a not a closed course, meaning there will be traffic. When run outside KL Forest Eco Park, runners should always run on side of the road facing traffic, and will be required to have a headlamp and blinker on after sunset.

This event will run concurrently with KL Forest Eco Park Endurance (KLFEPE) with support of Jabatan Perhutanan Wilayah Persekutuan.
