I have lowered my mileage goal this year to 500 miles in September. I have done this for 2 reasons.
1: My work commute is much shorter this year than it has been in past years.
2: I will be on vacation and unable to ride during a portion of September this year.
Anyone who knows me, knows that I will push to reach that 1000 mile mark anyway if it is at all possible. But if I do not make it, I have a smaller goal to surpass.
I may push on the stationary bike each day while on vacation. I do not typically log stationary miles for this challenge though.
