Not all states have been running 5k through the early stages of the season. Resulting in some of the nation's best athletes being left off the 5k national rankings. By using the MileSplit Conversion Calculator, we can get a look at what the national rankings could really look like.
The Top-1000 3 Mile times were converted to 5k and then merged with the Top-1000 5k times so far in 2015. The underlined/italicized athlete names indicate a 3 Mile time converted to a 5k.
Keep in mind this is based off of season best xc times and all courses are different.
