Saturday week 9

The day before the Luton marathon and just an easy swim to ensure I'm fully rested. Though not feeling well at work on the Friday and finding the swim hard work I'm no longer looking forward to the marathon.
Swim session comprised:

1200m as 200 f/s, 200 pull, 4x100 drill, 200 pull, 200f/s continuous

4x 200 on 3:20 (managing 3:05-3:15)

35 minutes starting 9:25pm , 44spl, but not feeling great
