An interesting lesson came to light during our drive from Colorado to the start of the Race Across America in Oceanside, CA. We are driving 2 Ford Explorers. Same model, same year, same everything - EXCEPT one is aero (no bikes on roof rack) and the other is non-aero (2 bikes on roof). We all know that makes a difference in fuel economy, but interestingly, it makes a significant difference! Upon each fuel re-fill, the "non-aero" bike required 10-15% more fuel!
This is a great reminder of why the Aerobar Edge is such a powerful training tool. If we were to drive to CA but never compare the fuel receipts, we wouldn't even realize the impact of the bikes creating the "non-aero" impact. As triathletes and time trialists, we "know" that sitting upright probably has an impact on our race results, but the Aerobar Edge now allows us to see EXACTLY how that impact plays itself out in terms of speed, heart rate, power and our own personal patterns around time in aero vs. upright positioning.
What gets measured, gets done. Are you measuring the single most important aspect to your racing results?
Onto the start line! (with the knowledge we need)
