Pacer
Turn a distance and target time into pace, splits and predictions.
Pacer is an offline running pace calculator for runners and coaches: pick a race distance and a target finish time and it instantly shows your pace per kilometre and per mile, your speed, and the even-pace splits to hold — with a live 400m track that runs your pace back to you. It also predicts your finish across the 5K, 10K, half and full marathon at that effort, and flips between km and miles in a click. Built end-to-end with AI as a single self-contained HTML file you can download from the source link and self-host.
