Tempo run at altitude

I did my 5.5 mile tempo run this morning. I ran along the Sunriver roads and bike baths out toward the airport along River Road. I got up early and started at about 7:15am hoping to get a sense of what it might feel like at the tri relay this weekend. I will definitely warm up for a significant amount of time prior to my run leg because it did take me a while to feel ready to go. I started out fast and clocked my first 2 miles at 7:00 min per mile, but I really started to feel the altitude after that point and got pretty tired out near the end of the run. My last two miles were in the 7:45 min per mile range so I think I went out a bit too fast. Glen is suggesting that I just go for it at the relay and see how fast I can run it...but I do think I need to pace myself at least a little bit because I can overdo it in those first few miles.

After my run we packed up our families and headed out for the 'Paulina Plunge', a guided downhill waterfall mountain bike tour along the Paulina stream. A bus picked us up in the Sunriver Village parking lot and drove us into the Oregon backcountry where we began a 2500 vertical foot descent on a single track in the high desert forest. Along the way we stopped six different times and hiked in toward the stream to play in waterfalls up to 40 ft high, plunge into deep pools, and slide down natural water slides. It was a total blast, ...kids and adults had a fantastic time.
