http://rideapart.com/2013/11/ways-to-stay-under-the-radar/ Rideapart just published this interesting article. I've been practicing some of these for a long time with great success. Are there any others you do? For example: I will only do "burst speed" in other words, pick a speed you want to do get to it and slow way back down to the speed limit. Kind of like Fartlek (speed play) in running or jogging. Fatlek, still makes me smile every time. What are your strategies?
