An Army officer with no apparent health problems died suddenly after a training run in North Yorkshire, an inquest heard.

Lieutenant Peter Rous, 25, of 1st Battalion Scots Guards, based at Catterick Garrison, took part in the five-mile run with about 100 other soldiers on November 3 last year.

The inquest, in Northallerton, heard Lt Rous complained of feeling dizzy about ten minutes before the end of the run and collapsed after he completed the course.

Coroner Michael Oakley told the hearing that an Army captain noticed Lt Rous was exhausted, but had claimed this was “not unusual”.

The captain gave him oxygen and found his responses and pulse were weak so put him into the recovery position.

Lt Rous, from Dennington, Suffolk, was immediately taken to a medical centre just metres away and later transferred to The Friarage Hospital in Northallerton, where he was pronounced dead.

A cardiac pathologist found his death was consistent with sudden adult death syndrome in a heart that was otherwise normal.

The inquest heard that sudden adult death is often caused by an unusual heart rhythm that can occur as a result of exertion, stress or exercise, and can be inherited.

The coroner recorded a verdict of death from natural causes.
