Following the previous day’s extreme tiredness, and once the day’s work was over, I was pampered more than ever with the best food, sweaty sports clothes unpacked and washed for me, and best of all, allowed to collapse on the sofa for much needed sleep.

I am finding that some days are good days and some are bad. The bad ones are mostly marked by niggles and concerns over possible injuries and the good days are significant for the lack of such things. After a slightly later entry to the pool than usual due to grabbing another hour sleep, today was a good day.

The slight shoulder pain was not a problem on the swim, and the knees did not hurt on the bike. And, despite having developed a huge mental challenge to set off on the 10km run each day, the legs seemed less heavy than the past few days. Without realising, I had run the 10km in 48 minutes, while well below race pace, it was as fast I had gone on any of the previous runs on the challenge.

Best of all, the niggles were minimal, so it was a great day. Thirty-seven done, just 63 to go.

As I do every day, I paid tribute to the police officers and staff who died on this date in the past, and today I remembered those who died on duty on December 6. They are:

1929 – Police Constable John Burr – Glasgow City Police

1941 – Special Constable John Stevenson – Ulster Special Constabulary

1942 – Special Sergeant William Grout – Metropolitan Police

1963 – Police Constable John Brown – Royal Ulster Constabulary, GC

2005 – Police Constable Vassili Bogomoletz – British Transport Police

Please support me in raising money to help build a fitting tribute to these and more than 4,000 who have died protecting us at the National Memorial Arboretum.
