Controlled pace runs

Here're the splits on two controlled pace runs this week (3 km warm up, 2 km cool down):

Feb 15:
km/pace/ave HR
1/5.59/165
2/6.20/165
3/6.59/167
4/6.29/164
5/6.16/169

Feb 18:
km/pace/ave HR
1/6.17/163
2/6.13/169
3/6.28/165
4/6.21/169
5/6.37/170

Both were on the day following a two-session training day (swim and bike), so some fatigue is present.
