Staff at Golden Charter donned sweatbands to mark four weeks of training remaining until a charity event where they will be challenged to cycle, run or walk 21km around Loch Katrine to celebrate 21 years supporting the Woodland Trust.
The Glasgow-based later life planning company has helped the Woodland Trust plant over 300,000 trees across the UK - equivalent to woodland the size of 250 Hampden Park football pitches.
21 years ago Golden Charter decided to begin making a regular donation to the Woodland Trust, and this year total donations will reach just over £994,000. It is hoped sponsorship for the celebratory Golden Challenge event will take the total beyond £1million.
Ronnie Wayte, Chief Executive at Golden Charter, said: "Golden Charter has been in partnership with the Woodland Trust since 1995. To celebrate this amazing milestone, we are hosting the Golden Challenge on Saturday 3 September, a joint charity event where staff will be challenged to trek, run or pedal 21km around Loch Katrine.
"The event is already shaping up to be a great day out with a voyage on the Steamship Sir Walter Scott, a delicious barbecue and the services of professional massage therapists to soothe weary limbs.
"We are immensely proud of the contribution we've made towards supporting the work of the Woodland Trust over the years but this year we're aiming to raise £21,000 from this event, which will take the total raised to over £1m."
