So I finally got around to buying a decent floor fan for my training sessions. Oh my gosh, what a difference.

I know the following example isn't exactly scientific, but I think in general, it speaks to the benefits of using a fan while on the trainer.

Some points:
- workout is Sufferfest "A Very Dark Place"
- effort and cadence instructions were followed (more like attempted)
- 1st workout (in BLUE without fan) - beginning of Feb '12. 2nd workout (in RED with fan) - end of March '12
- both workouts done after supper, about 7pm



Not only has my overall speed increased, but my heart rate was overall lower, especially during recoveries. Even during periods of higher cadence with workout#2 with fan, heart rate still remained lower than workout 1.

Again, not overly scientific, as there are a myriad of factors that may have affected my performance (meals, alcohol the day before, hydration etc), but physically, I was not nearly as drained and demolished than the session without the fan.

Bottom line, invest in a darn fan.
