Run - Road (warmup) 18:56 [2] 4.0 km (4:44 / km)
ahr:131 rhr:46 slept:6.5
New HRM (with splits). Using formula for 'aerobic base' found after reading this AM's attackpoint discussion. Set alarm at 138 and made sure to stay below this for 3 of the 4 legs - Base Building. Every little rise kicked the HR up - it was a nice pace, just shows that I probably push too hard, even on easy runs.

Run along the river, slowing down if HR went above 138 (presumed aerobic base). Distance a little long as I forgot to hit the split until I got up to stream crossing.
Ice is finally gone....

Easy on the lower part - then pushed as hard as I could on the upper section past low spot. Trying to see what my 'measured' maximum might be. Managed to get within 6 beats of calculated max. Will repeat this occassionally to see what my real max might be.
