Today's swim started off being hard work and didn't get any easier. Basically I felt drained and de-energised from the outset. I'd imagined that I'd swum for longer or done a greater distance than in the preceding weeks but the cumulative data say otherwise. Friday's swim was the longest time and distance I've done so far in 2018 so maybe that took a little extra out of me.
Nonetheless tomorrow must be a rest from swimming, which is fine as I'd like to go for a morning run.
