A 90-Year-Old Explorer's Thames River Challenge to Save Britain's Rainforest

Robin Hanbury-Tenison, a decorated explorer and conservationist now in his 90s, is water-biking 104 miles down the River Thames from Oxford to Teddington Lock over four days. The challenge is raising money for a research station — one that would be a first for Europe.
The target is £150,000. That amount funds part of a larger effort by the Thousand Year Trust to build Europe's first dedicated research facility for Atlantic temperate rainforest, to be located on Bodmin Moor in Cornwall. The Guardian reported in April 2025 that the total facility will cost around £750,000. Yahoo News UK covered the Thames challenge on 4 June 2026.
What is Atlantic temperate rainforest?
Atlantic temperate rainforest is a type of woodland found in wet, oceanic climates. It thrives in places with high rainfall and is marked by thick layers of mosses and lichens covering trees and rock. This ecosystem once stretched across much of western Britain and the Atlantic coasts of mainland Europe. Centuries of sheep grazing, logging, and drainage of wetlands have shrunk it to small, fragmented patches. Cornwall's Bodmin Moor still has some of these conditions intact, which is why it makes sense as a location for restoration work and long-term study.
Why a fixed research station matters
A £750,000 station on Bodmin Moor would be permanent infrastructure — not a temporary field camp attached to a local estate. That matters because understanding and restoring temperate rainforest requires decades of data. Scientists need to monitor what happens over 10, 20, or 50 years, watching how the ecosystem responds to rewilding efforts. The Thousand Year Trust's name itself reflects this ambition: it signals that conservation goals in this biome work on the scale of centuries, not the five-year timelines of most funding cycles.
Without a dedicated base, researchers piece together work across different seasons and funding grants. A permanent station provides continuity. It lets teams develop and test strategies for expanding these rare woodlands across larger areas. It creates a physical hub where knowledge can accumulate.
The physical challenge
The Thames route from Oxford to Teddington Lock covers the non-tidal section of the river — roughly 104 miles of water travel. Completing it in four days by water-bike is genuinely demanding endurance work, not a symbolic photo opportunity. Hanbury-Tenison has spent a lifetime on expeditions — he founded Survival International and led major Amazon explorations — so the physical scale fits his track record rather than contradicting it.
The funding puzzle ahead
At £150,000, the Thames challenge covers 20 percent of the station's cost. The remaining £600,000 needs to come from somewhere: philanthropic donors, conservation trusts, government funding, or a combination of these. Whether it arrives determines whether the station gets built on the timeline the Thousand Year Trust has sketched out.
Hanbury-Tenison's name recognition in conservation circles carries weight. His credibility — built over actual fieldwork, not simply raised through marketing — gives the trust a communications advantage that a standard grant application cannot match. Legacy donors and conservation networks respond to proven explorers. But visibility helps only if it translates into pledges and, eventually, matched funding.
The real test is whether a high-profile water-bike challenge can unlock donations beyond the immediate £150,000 goal. Can it persuade larger funders to commit the remaining capital? Can the trust sustain a £750,000 facility — not just build it, but staff and maintain it — over the multi-decade horizon it intends?
