Mapping accessible bike paths for cyclists 55+ around Rīga's hydroelectric dam and Daugava River corridors
About the Author
16 Years of Cycling Route Research
Andrejs grew up in Salaspils, just kilometers from the Rīga hydroelectric dam. That proximity shaped his childhood and later his entire career. He's spent the last 16 years studying how water infrastructure connects to local landscapes — and more importantly, how it creates opportunities for cycling.
After graduating from Riga Technical University with a civil engineering degree, he worked for the Latvian Road Administration. But something shifted in 2012. His parents were getting older, and they wanted to stay active. He couldn't find reliable information about safe, manageable cycling routes near the city. So he built one.
That personal project became his life's work. Over 12 years, he's personally cycled over 400 kilometers of pathways around the Daugava left bank. He's tested these routes in every season — spring floods, summer heat, autumn rain, winter ice. He's documented elevation profiles, surface conditions, rest points, and accessibility features that matter most to recreational cyclists aged 55 and older.
What drives him isn't abstract infrastructure planning. It's practical problem-solving. Older Latvians want to stay active. They deserve reliable, detailed information about where they can actually cycle safely. That's what he provides at Positiveplumbingqld Three SIA.

"Older cyclists don't need fancy equipment or extreme routes. They need reliable information about places where they can actually ride safely. That's what I've spent 12 years documenting. The Daugava left bank isn't just infrastructure — it's a network of real cycling opportunities that've been underutilized because people didn't know they existed."
