What a difference a year makes!
Compare the chart above, with the sectional times chart from last year's Winter Derby, in the post below. In 2016, Grendisar won a steady race, where almost all horses managed optimal efficiency. This year shows an unusual pattern to the race pace, a very slow start of the race, followed by a burst of speed.
While favourite, Mutakayyef, didn't run and last year's winner, Grendisar, didn't manage to make it into the winners enclosure this year, you should have a look at the Sectional Tools tab on At The Races, which shows the horse efficiencies (or lack thereof) in 2017.
