Master Sheet to tabs based on number typed on tab?

Thank you for your time. I am working on a spreadsheet to do manual time tracking for a cross country meet for kids. I would like to input all my participants data into the master. Then the day of the race I will use each tab as the group run to enter the data.
For the KG tab, runner 101 crosses with a time of 5:23. I want to enter time 5:23 then number 101, then have the spreadsheet auto-populate the with information off the master - first name, last name. We will use the sheet for years to come due to the cost of using automated timing devices for kids races. I appreciate you help!

I have attached my sample sheet.
