Today was a tough day. Just three hours sleep because of stomach pain, and I felt drained.

The swim was OK but I couldn’t wait for the cycle to finish – it seemed to go on forever as my energy dissipated. And then when I set out on the run, I felt exhausted after the first few steps.

I still do not know any of the times – I am sure they are similar to recent days but they took so much more effort.

My Garmin watch tells me how much recovery I need before I start the next exercise, it says 46 hours. Some chance!

I made it through another day and sights are set on the next milestones – one month and one third of the challenge – three and six more to achieve these.

I had a much-needed massage from Nicolette at Elite Physical Medical practice in Aylesbury and she was shocked how tight and painful my muscles were. Virtually every part of my body was sore but I know I will sleep well after this treatment.

If anything, the aches and pains are a signal to be sensible with the effort and ensure I don’t suffer more injuries, stop trying for good times each day.

I am doing this very difficult challenge to complete 100 Olympic-distance triathlons in 100 days to raise awareness of and money to build a fitting memorial at the National Memorial Arboretum in Staffordshire.

I am so grateful to Warwickshire Police Chief Constable Martin Jelley who offered to raise money at a conference he is chairing today and delegates working in the Professional Standards arena gave £1,517 towards my challenge. What a boost, thank you.

Each day I pay tribute to the police officers and staff who have made the ultimate sacrifice to protect the rest of us.

On this day (November 26), I have pleasure recording the smallest number of any day so far of those who lost their lives on duty:

1756 – Watchman Joseph Forrest – Cripplegate Ward, City of London

1893 – Police Constable John Goddard – Metropolitan Police

1914 – Sergeant William Jackson – Sheffield City Police

1916 – Police Constable Frederick Treasure – Gloucestershire County Constabulary

1940 – Police Constable William Armstrong – Royal Ulster Constabulary, GC

Please help me pay tribute to these and say a huge ‘Thank you’ to every police officer and member of staff who put their life in danger today and every day to keep us safe. Please donate what you can here.
