    Training is going well, but the weather isn’t exactly cooperating. I did a 3 hr hard & fast ride last night and got caught in the worst electrical storm. Total down pour mixed with hail and thunder and lightening all around me. I got drenched and wasn’t really anywhere convenient to pull over, so I just hammer through.

    Same thing today, but this time I was on Glebmore res. Luckily it’s just warm enough outside to stay warm through it by stoking the furnace with about 250 watts.

    I’m trying to get out to the lake for as much training as possible this week because Helen and I are cycling Sonoma in California next week. I’ll be on the M5 for that.

    I got some decent speeds today on Glenmore despite the rough water due to the winds. 11.3 kph average speed for a 5.8 km loop of the entire lake at 150 watts. most of the lake was ripples with sections of 6 to 8″ waves, and even some waves breaking over the deck. Updated speed data below:

    Observations
    1. Every 5 kph of wind equates to .1 kph decrease in speed
    2. Big rudder is .6 kph slower than small rudder. Small rudder is .1 kph slower than no rudder
    4. Paint vs packing tape was worth a speed increase of .1 kph
    5. Elliminating the prop strut is worth an additional .1 kph in speed.
    6. Counter clockwise loops at Elbow Valley lake are worth an additional .2 to .3 kph average speed due to current.
    7. remove the seals and backing off the lock-nuts on the gear box are worth an additional .1 kph average speed.
    8. The narrowed 1/4″ spring steel shaft compared to the 3/8″ stainless shaft is worth .1 kph speed increase

      Do you realise you were the highest point on the lake!!

      11.3kph is good for the conditions.

      You may want to check the fire situation in California. Many areas are very smoky now. That includes areas far away from any fire. Not healthy.
