To round up or not to round up at the end of the month

I had set a loose goal to run 125 miles and bike on the trainer for 250 fake trainer miles during the month of May. I added up my totals yesterday and got 121.85 for running and 241.5 for cycling, with another trainer ride planned for today.

My high-tech training log of a supplemental post-it note and a spreadsheet.

I briefly considered doing 8.5 on the trainer and a quick brick of 3.15, but then decided I didn't care that much. Plus, I was sore and my knees felt like they could have used a break. It's very unlike me not to want to end on a round number, but I figured 121.5 was close enough.

Should I have done a 8.5/3.15 brick? What combo would you have done?
