Interesting session today... 3 mile effort, jog recovery, then a 2 mile effort...
Interesting (but not altogether surprising) that whilst I still finished in a relatively similar position within the group, there was a noticeable gap compared to when we do hills.
Also was interesting that the hardest part was getting going again after the recovery, it really knocked my rhythm out, although some people struggled a lot more than me with this and had a terrible 2nd effort....
