At 5:45 we all walked less than a quarter mile to the start line. The race started right at 6. The first 11 miles are easy and mostly downhill with the exception of two tiny hills. The rolling hills started after mile 11. It's iust important to remember that even though you are going uphill, the downhill on the other side of the hill is even bigger. The las big uphill happened around mile 16. From there, there are some uphills, but much smaller. This is the section where I seemed to struggle more. The bank on the roads did add an extra little challenge in this section. Sometimes they were quite steep. The last two miles went quickly and there is a little uphill right as you turn the corner to the finish. It's really not bad at all.
As a side note, I only noticed the elevation on the uphills. The rest was fine.
