ONE. MORE. LOOP. #Run4Diabetes!

SATURDAY MAY 4 - 2024!

Welcome to the 3rd edition of WINTER BAY Backyard Ultra 2024 - the race in central Stockholm - with start/finish right next to Liljeholmens T-bana!

The 1st edition in May 2022 was extremely popular & a sold-out running festival with 240 st registered participants (ca 180 st started). The winner Mai ran 41 loops & was awared a spot in the Swedish National Team in Backyard Ultra World Cup in October 2022.

The 2nd edition took place in May 2023 with fewer runners (ca 130) but who created a truly fantastic weekend with amazing atmosphere in great weather. The winner Szilard Fodor from Hungary was the last one standing after 30 loops.

We are delighted to announce that we again 2024 can offer the winner a "Silver Ticket" = a spot in the Swedish National Team in Backyard Ultra Satellite World Cup!

All participants really praise the fantastic course which is beautifylly varied along lake Trekanten, rounding the magnificent Vinterviken & bck again on the other side of the lake to Trekantsparken.

Everything that has to do with the race will contribute to our charity initiative #Run4Diabetes  to support Barndiabetesfonden (The Swedish Child Diabetes Foundation).

By WINTER BAY Backyard Ultra 2023 we raised an incredible 23.433 SEK!

- The starting line (& finish line) is located at the small but beautiful Trekantsparken, just 100 meters from the exit of T-bana Liljeholmen. Also called the "Loop Area".

- The 1st kilometer will follow the south side of lake Trekanten on prepared trails with sections of wooden paths.

- The 2nd kilometer will take you through the beauiful Vintervikens Trädgård on gravel/macadam/asphalt paths.

- The 3rd kilometer (almost) you will be running on asphalt paths leading up to the top of Örnberget, where you will face the only steep uphill on the course. Feel free to walk.

- Kilometer 4-5 (almost) starts with a rather heavy descent down to the water, where you will follow Vinterviken (Winter Bay) along lake Mälaren on prepared trails.

- Kilometer 6 (almost) will take you through the residential area of Gröndal along Gröndalsvägen on asphalt pavements.

- The last kilometer (almost) will follow the north side of lake Trekanten, before you reach the loop area & the finish line for each loop.

- ... Then you run & repeat this loop under 1h, until there is just one competitor willing to run one more loop under 1h. Remember, the next loop is always cooler than the previous!
