How tough was that

I had my swimming sessions today.  30 mintues of 1:1 and then the hour group session.  I knew I was tired after yesterday's 20 miler but once I got in, I realised just how tired.  She had me doing length after length which as so tough but I am still making great progress with my stroke.

Then is was the group session.  I say group but there was me and one other; I guess people were enjoying the holiday weekend.  So, it was 6 laps of this drill then 6 laps of another.  Thankfully, the other guy wasn't a speed demon so I got a little rest before he finished each set of drills.

I'd love to know how many laps I did.  I'm pretty sure it was over 60 lengths of the 20 meter pool.  No to Devon and cycling.
