Day 15 – 20 mile run

The plan was to run the first 5 miles at 8 min/mile pace, the next 10 miles at 7:30 min/mile pace and the last 5 miles at 8 min/mile pace.

Well I nailed it:

  • The average pace for the first 5 miles was 7:56
  • The average pace for the next 10 miles was 7:21
  • The average pace for the last 5 miles was 8:02

Conditions: Good day, not too warm/not to cold.

Remarks: I found it difficult for most of the run to maintain a steady pace. I kept running too fast, the first 2 miles in particular I felt I was nearly walking I was going so slow 🙂

During the last 2 miles my mind decided I needed to slow down, and it wasn’t until I did a check (is my body ok – yes, is my breathing ok – yes) and I discovered it was in my head was I able to continue and get nearly back to 8 min/mile pace.

What else to say? – Well I ran well and enjoyed the run, I kept smiling to myself when I realised the pace I was running and how comfortable I felt, in particular when the pace increased into the 6 min/mile area (6:00 –> 6:59)

The route was very hilly, the hills for the last mile were hard.

Recovery: I feel good – The main area for concern is my back (left hand side, under my shoulder blade)

Heart Rate: Average: 139 Max: 183

1 thought on “Day 15 – 20 mile run

  1. The feedback from Peter was – too fast.

    I ran too fast, I need to maintain control of my pace, I can’t allow myself to do this on race day.

    So what is my pace for the Marathon – 7:40 min/mile pace. this will bring me home in 3 hours 21 minutes.

    So the target is to run in 3 hours 20 minutes.

    The idea is I start for the first 1/2 Marathon at 7:40 min/mile pace and if I feel good at the 1/2 way point I can up the pace – slowly not like a rocket as I did with Charleville.

    Maybe getting my pace for the second half somewhere between 7:20 & 7:40 min/miles.

    I feel confident about this pace.
