Chiswick RNLI crew members took time out from a gruelling 21-mile charity walk to have a quick break with youngsters at a Chiswick infants school.
Volunteer life savers from Chiswick RNLI marched the Thames barrier path from Teddington to Tower Bridge in full protective gear on Friday as part of the organisation's SOS Day.
Along the way, they stopped to speak to pupils at Strand-on-the-Green Infant and Nursery School.
Marc Newton, head teacher of the school in Thames Road, Chiswick, told the Chronicle: "We found it really funny that they were calling at our school just before they stopped at Parliament, it's quite an amusing contrast.
"We've been collecting for Chiswick lifeboat station for three or four years now and have always given them priority.
"Because we are so close to the river, they come by on their boat to collect the money we have raised and the children can go right up to the river bank to hand over it over. Then they do a few donuts in the water and whizz of back to the station. The children love it."
SOS Day is the biggest event in the RNLI's fundraising calendar.
Martin Blaker-Rower, crew member at Chiswick lifeboat station, said: "It's our Comic Relief, if you like. Fundraising happens all year round, but SOS day is when we encourage as many as possible to identify with our mission to save lives and help support us in any way they can.
"We are based at Chiswick, but via four lifeboat stations along the tidal reaches of the Thames, situated at Teddington, Chiswick, near Embankment and at Gravesend, we provide search and rescue along miles of the river.
"With such a large area to target on SOS day we just couldn't decide where to concentrate, so we figured we'd do as much of it as we can, hence the 21 mile trek."
In keeping with the spirit of the day, where events are organised around the theme international distress signal SOS, the event was dubbed 'Saunter or Scamper'.
The crew raised money in sponsorship as well as from collectors out and about along the route.
