Mallory Richard writes a regular column for IRunFar called “Running The Numbers”, which uses quantitative data to talk about trail and ultrarunning. We discuss the pros and cons of the current athlete ranking systems in our sport, interesting performance insights from the UTMB and Golden Trail World Series events, and other interesting topics like how often runners improve their performance at a given race.Sponsors:Rabbit - use code Singletrack20 at checkout on their website (https://www.runinrabbit.com/discount/SINGLETRACK20) to get 20% off your next orderFeetures - use code Singletrack20 at checkout on their website (https://feetures.com/) to get 20% off your next order.Kodiak Cakes - use code Singletrack15 at checkout on their website (https://kodiakcakes.com/) to get 15% off your next order.HVMN - use code Singletrack20 at checkout on their website (https://hvmn.com/SINGLETRACK20) to get 20% off your next order or 30% off your subscription.Links:Running The NumbersFollow Singletrack on Instagram, Youtube, and PatreonSupport the show
