You hear, read, and observe that drafting behind another rider saves you energy. Do you know how much? This past Saturday two handsome fellows went out for a ride. They picked a mostly flat course for a 20-min effort and time trial. They both weigh the same, ride the same road bike, road on their hoods but with an aggressive posture, and were both equiped with power meters. The lead gentleman buried himseld over the course of this 20 minutes, holding back his own vomit, and produced a stunning average power of 313 watts and a normalized power of 316 watts. The gentleman following him stayed on his wheel in his draft, shouted encouraging words, and took in the scenery.
How many watts were produced and saved my the gentleman drafting?
A. Avg power of 281 (saving 32 watts), npower of 291 (saving 25 watts)
B. Avg power of 271 (saving 42 watts), npower of 281 (saving 35 watts)
C. Avg power of 261 (saving 52 watts), npower of 271 (saving 45 watts)
D. Avg power of 241 (saving 72 watts), npower of 251 (saving 65 watts)
E. No PRF teammate can produce that kind of power
