Comparing the Mas 4/5 Cobb Park and State Champ Cat 4
- Mas 4/5 46:20. 18.6 miles. 24.1 mph 212 avg/ 246 NP VI 1.16
- Cat 4 46:36. 19.6 miles. 25.3 mph 229 avg/249 NP VI 1.09
So I’m trying to figure out why in the two races above I’m able to be an animator in the Cobb Park race, and in the State race, couldn’t do jack. At first glance, the numbers suggest pretty similar races (note esp the NP). The speed suggests one difference, but part of that difference can be explained by the fact that the State race course had a decent downhill section. For me, the big difference comes in the VI (variablity index). The average and the norm for the State race are much closer, meaning that we were on the gas more often with less coasting. An even more telling stat isn’t represented in the summary are the # of bursts over 110% over threshold for at least 15″ (I used the find function in wko+ to figure these out). In the Mas 4/5, I had 13 such bursts; in the State race, 25, so nearly 2x the number. More than anything, I suspect that what zapped the legs and left me unable to move up, let alone attack as planned, in the last few laps. Take home lesson here — might need to reintroduce some microburst workouts into the mix. Tactically, need to stay closer to the front (duh!) which should eliminate some of the “burstiness.”
