Update

Thursday 1 March - Running - Hill session (1 hour)
Sunday 4 March - Swim (drill session, 1 hour)

Today: Double session!

Did a 6 mile run at lunchtime and didn't feel very sharp. My back is still playing up, but is improving. Legs felt heavy towards the end, but it was quite warm and I could have been slightly dehydrated (I didn't take any water with me).

In the evening I went to club for a hard, hard swimming session (2,400m). It looked something like this:

200m
6 x 100m (every other 25m - drill)

5x100m x 3 (various intensities, including hard)

100m swim down

First time I have doubled up training on a day, I think this will become the norm for a Tuesday from now on.
