General
This study aimed to evaluate the perception of time under different conditions (rest, during exercise, and post exercise) as well as the influence of different exercise conditions (e.g., versus an opponent or not). It is an interesting topic and should have a wide readership. The authors are mainly encouraged to focus the Introduction as well as expand the Results section. It would also be of value if the authors could highlight the immediate real-world practical applications that their findings will lead to.

Specific

Introduction
Please consider just introducing the most relevant background information. It appears that the major point of the Introduction is just the impact of external stimuli on competitive sport, especially as it relates to the perception of time.

Methods
The Declaration of Helsinki includes that all investigations involving Humans preregister on a publicly available data repository. Was this done?

When using the RPE scale, it is important to anchor baseline and maximal. Was this done?

Why was RPE chosen to be collected as opposed to OR in addition to the FELT Arousal scale?

Is there fitness data available for the participants used (e.g., VO2max, FTP, etc.)? What experience do they have with cycling?

Result
In terms of organization, it may be beneficial to create individual sections within the Results as opposed to one block paragraph.

It would be beneficial to include statistics for the interaction term and each main effect (if there is not a significant interaction). In the presence of a significant interaction, please describe how the interaction was decomposed i.e., comparisons collapsed across X… or independent of X, there was no difference between…

Discussion
Please discuss/explain the relevance/link between this study and the alluded to trials of performing exercise at a fixed RPE

European journal of applied physiology, 118, 2499-2508.

Are there any limitations/experimental considerations that the authors would like to include?

What are immediate practical applications available based on these new findings?
