- Abstract summary: In May 2021, the site runnersworld.com published that participation in ultra-distance races has increased by 1,676% in the last 23 years.
Nearly 41% of those runners participate in more than one race per year.
This work aims to determine how the runners performance can be quantified and predicted by considering a non-invasive technique focusing on the ultra-running scenario.

- Abstract: In May 2021, the site runnersworld.com published that participation in
ultra-distance races has increased by 1,676% in the last 23 years. Moreover,
nearly 41% of those runners participate in more than one race per year. The
development of wearable devices has undoubtedly contributed to motivating
participants by providing performance measures in real-time. However, we
believe there is room for improvement, particularly from the organizers point
of view. This work aims to determine how the runners performance can be
quantified and predicted by considering a non-invasive technique focusing on
the ultra-running scenario. In this sense, participants are captured when they
pass through a set of locations placed along the race track. Each footage is
considered an input to an I3D ConvNet to extract the participant's running gait
in our work. Furthermore, weather and illumination capture conditions or
occlusions may affect these footages due to the race staff and other runners.
To address this challenging task, we have tracked and codified the
participant's running gait at some RPs and removed the context intending to
ensure a runner-of-interest proper evaluation. The evaluation suggests that the
features extracted by an I3D ConvNet provide enough information to estimate the
participant's performance along the different race tracks.

"Learning to run" competition was to train a two-legged model of a humanoid body to run in a simulated race course with maximum speed.
All submissions took a tabula rasa approach to reinforcement learning (RL) and were able to produce relatively fast, but not optimal running behaviour.
We demonstrate how data from videos of human running can be used to shape the reward of the humanoid learning agent.
