After the urban chaos of India, the last episode of the series once again found us travelling for days to people living at the ends of the earth.

Manus is stuck out in the middle of the ocean with nothing to stop the waves for thousands of miles.

The overnight journeys, lack of sleep and nausea made me think we were in for a pretty unpleasant week.

Fortunately, the reef around the islands provided some shelter.

By the time the shark fishing and the race in the open sea came round we'd all gained our sea legs.

The Titans live in stilt houses over the sea on the edge of densely forested islands. This meant there was nowhere on land for us to camp.

The only way to accommodate the crew, store filming equipment and charge the batteries was to get a live-aboard boat.

Despite having to share a very small cabin next to the engine room, it was much more comfortable than the normal tent accommodation.

The crew on the boats loved to fish while we were busy filming the athletes. This meant we had a plentiful supply of fresh fish and squid to welcome us at the end of each long day.

To film the race itself we had to have a much bigger crew than usual to cover the 6 athletes and 30 or so locals across the 25 mile race course.

We'd tried to find a helicopter to give us aerial coverage but the nearest one was an entire day's flight away so was impractical.

We had 7 cameras spread around the course on larger versions of the competitors' outrigger canoes with a small outboard engine.

These canoes were gathered from many of the outlying islands and were usually used for fishing. They were capable of staying out at sea for days and weeks at a time.

On the final day of filming, the boat I was on, stuck with JJ in the dash across the mercifully flat sea for the finish.

Although he didn't trouble the leaders at the end he pushed himself to the point of collapse in the equatorial heat and it was a fantastic effort just to finish.

After that, all we had to do was enjoy the party that night on Peli beach and reflect on the one of the most difficult but one of the most enjoyable series for all involved.
