Macon 5k. Ran this race last year in 25 something finished 4th in age group. I wanted to me in relative good condition this year. I have been training only aerobically for the last 7 weeks to build endurance. I was hoping to go under 24:00. Last year 3 in AG was 24:15. I worked last night and did not get to bed until after 3 am. Up at 4:50 because the race was about 75 miles away. My back was twitching a little. Decided to go for a time of 25:41 / 8:18 pace which a took from a race predictor chart. Started slow to test the back and since I had not done a pace over 13:00 in 7 weeks. 1st mile 7:57 2nd mile 7:23 3rd mile 7:19 .1 mile :11 22:52 Does the Garmin 305 go into auto stop in tunnels. The last mile was off by :30 from the clock and 0.06 miles off from race distance. I checked with some club members and there times matched the clock. I had :30 in the pause section of the 305 and 2 gaps( blank space) on the course map. Now I need to find a good space to display my trophy!

Congrats on a good job and award!! I don't have a garmin, but have read that garmin automatically readjusts for true distance once you're out of a tunnel and pick up the signal again (a recalibration based on satellite repositioning) - maybe someone will confirm this ... Bill

Congrats on the race! Do you the Auto Pause turned on? If so, turn it off. With it turned off, I've found that it must do some kind of auto correct thing as havanarnr suggests.

Congratulations for you! Esp. w/ the work & no sleep.

Congratulations on the new PR and for your placement finish.
