Swimming
1600M - 00:45:44 in 18M pool at Gym

Warm up 200M (WU 200)
8 X 50 M Drills (Kick only / Swim fist / Doggy Paddle / Arms only) (8X50 Drill)
4 X 125M with 20 secs rest between intervals (4X125@20secs)
8 X 50 M Drills
100M cool down (100M CD)
Total 1600M

Swim felt really good today.  I changed things around a bit on the Leg Kick drill.  I had read about doing this drill on your back as it makes breathing easier but still gets the effect on the legs.  It worked really well - the legs got a good workout and the breathing was easy.
overall a good session today and a good steady average pace.

Running
00:45:00 - 4.15 Miles (00:10:51) per mile / HR 157bpm Z3 87% Max)
I am starting to get pretty annoyed and frustrated with slow running with a high heart rate.  It is Flippin' annoying! I am a bit baffled now as to why it is normal and all good some times and other times it will not come under control.
Any ideas from anyone - PLEASE??
