Some swimming - and a two-stage run

I have no idea what happened today, but while swimming with 4 adults and 6 kiddiwinks (not that that is relevant), when I did my little swimbling thing - I found myself doing 17-18 strokes per length. What was THAT about...?
I have no idea what I was doing differently - it didn't feel any different - I'm at a loss!!!
Good tho
:o)

The two stage run was about - running with Pix and Zina - and then going for another slightly faster effort on my own
'twas very nice!

The first bit -

Distance: 3.5 miles
Time: 45:56
AV pace: 13:04m/m
AvHR (for me) 135pm

Mile	Pace	Time	AvHR
1	12:13	12:13	135
2	12:46	25:00	137
3	13:50	38:00	135
0.5	14:10	45:56	132
3.5	13:04	45:46	135

Was almost instantly sent back out for a little plod on my own. So I thought that I'd give the legs a little stretch, and put in a bit of an effort type thingy! That was the plan - and that was what I did. I chose a route with some nice undulations in it, and one short sharp descent (Fell running practice..??!!). It was good to run more quickly for a change - quite enjoy doing that :o) The numbers:

Distance: 4.96 Miles
Time: 38:10
Pace: 7:38 min/mile
AvHR: 173bpm
