February 11th..intervals

Bought a new battery for HR monitor which is now working
Also attached new 'Rifle' seat cushion to bike. Readjusted X-seam due to foam thickness but not sure it's perfect yet. Still training in sandals and am probably giving up some power in the process especially at higher wattages.

1. 20m easy ramping up from 150 to 205 watts by end

2. 4X5m intervals: 5m on/1m off: Wattage and HR listed

    1st...300W w/final HR of 148. Could not exceed 70ish rpm w/selected gear,
                     Shifting down to next lower gear for 300W seemed too low.
    2nd...240W w/final HR 138. Used one gear lower to active recover and raise rpm to 80-85
    3rd... 255-265W w/final HR 140 w/ rpm closer to 85-90
    4th... 260-270W w/final HR 142w/rpm near 90

HR dropped from 142-86 in two min.

3. 20 min. at easy/recovery pace of 170-205W
HR 118-86-72 in two min.

What I learned: start w/lower wattage on first interval and ramp up
Select/know which gear in advance to use to generate 90rpm at 245+W

Total time: 73 min
Ride time:  65 min
Calories: 944
Distance: 22.74 miles
