Tow segment data · Day 03

Sandy RAN Beaver RAN

This 195-mile tow leg from Sandy RAN to Beaver RAN on Day 03 averaged 1.61 mi/kWh, +31% the 1.23 mi/kWh ledger average, climbing about 4,440 ft, into 12 mph of light headwind penalty, around 77°F. That works out to a full-pack tow pace of about 227 miles on the 141 kWh pack.
