No start at all for my Garmin.....I must have left it turned on for over 24 hours. When I tried the 'on' button at the school where I start, I realized the battery was flatter than a tack. For a few seconds I felt completely bothered and bewildered! How was I to do a tempo session knowing neither distance nor pace? Decision made : go the same route as previous tempo runs and feel for the pace. I did this but how successfully I'll never know!
The program was : 8km
5km @ 6:40m/k
1 km cool-down.
In reality what I did was use my mobile phone where I could see the time and did a 10 min warm-up, ran fairly hard for 35 min in the same location as last week and then a cool-down jog back to the car. I think this was pretty much how I would have run had the Garmin been working....hope so; if not, not much I can do about it!
