Swim Sessions: Threshold 25s + 100s

I love a threshold swim session. A session where you raise your heart rate – and then keep it there for a good length of time!

A mental and physical challenge, which is hugely satisfying when it is all over!


Swim Sessions: Threshold 25s + 100s

Threshold Swim Sessions


We did a different type of threshold session recently. Instead of a 20 x 100m set (or a variation of this), we did some 25s and 100s. This set was 2,000m of pretty hard work.

During the set we were aiming for:

  • Strong Pace
  • Sustainable Effort
  • Sound Technique
  • Strong Mental Focus

I think we ticked all of those boxes!

“That was my type of session!”

“Really enjoyed this session including the short intervals on the 25s. Felt good throughout and did a quicker average than I was expecting. Probably the most consistent and smoothest session I can remember.”

“Might have been a 100m PB – 1.30”

The Session

Warm Up (200m)

2 x 100m smooth and relaxed (20s)

Main Set (2200m)

Two sets of …

20 x 25m – a strong pace that is just about sustainable for all 20 x 25m (15s)

5 x 100m – a strong pace that is just about sustainable for all 5 x 100m (30s)

4 x 25m – easy (15s) 

Cool Down

Easy swimming to finish

Scaling

We reduced the session slightly for some of our lanes. It was 16 x 25m and 4 x 100m instead.
