Mr. Houghton, the floor is yours for the Q&A session.
Bob Houghton -- Vice President of Investor Relations
Thank you Donna. First, I would like to thank the many analysts and investors for taking the time to submit questions after our earnings release yesterday. For today's Q&A session, I will frame-up the question and then turn it over to Bob or Scott for a response.
Our first question comes from Tom Wadewitz with UBS; Jack Atkins from Stephens; and Dave Vernon from Bernstein asked similar questions. What are the primary factors driving the significant fall off in net revenue performance, year-over-year from up 3.5% in the second quarter to down 8% in July? Other factors that could cause July to be meaningfully worse than what you'd expect for August and September?
Bob Biesterfeld -- Chief Executive Officer
So good morning, Tom, Jack and Dave. Thanks for the question. Results in second quarter decelerated throughout the quarter, as our net revenue dollars, per load, decreased sequentially week-to-week. If we look back from week 22 to week 26, we saw a pretty significant drop-off in our net revenue per truckload, until we reached a bit of an equilibrium at around 5% below our historical trailing 10-year average, during week 26.
So, we've seen a slight uptick in net revenue per load, during the last week of July, but we do anticipate continued pressure on that key metric of net revenue per load, based on what we're seeing in the marketplace and where we feel like we're needing to reprice our business, in order to maintain and take volume in this market.
So, by repricing at the current market rates, our win rate on contractual business is really higher than we've ever experienced at any time. So, we see that as a real positive on the bids that are coming through our process in the second and third quarter. But, these awards are coming in at lower margins than what we saw last year. So, this coupled with contractual customers seeking mid cycle price relief, and really the lack of spot market freight, these factors are going to continue to put pressure on net revenue, per load, through the balance of this year when comparing to the second half of last.
So, it's clear that our path to EPS growth in the second half of this year is really going to need to be driven by meaningful truckload volume growth. While, I'm not going to attempt to predict the results for August or September, at this point, relative to July; sequentially our growth rate did slow through Q3 last year in truckload. So, the comps do get somewhat more favorable, as the quarter progresses, but really our success in third quarter isn't going to be driven by our comps alone.
