Astronaut Tim Peake answering questions ahead of running a space marathon

Tim Peake is answering questions ahead of running the marathon in space this weekend.

The British astronaut will run the full 26.2 miles on a treadmill on board the International Space Station.

On Earth, a team of UK Space Agency and European Space Agency colleagues will run with him in support of the Prince’s Trust.

The former test pilot rocketed up to the space station in December last year and will be in space for six months.
