Hot but not so hot

It was a hot and humid weekend of training. Saturday I was scheduled for 16 mile long run with 15 min pick-ups to 9 min pace. A rice cereal, rice cake with Nutella at 4 am so everything would be digested Started the run at 6:30 am with 30min warm up. Temp about 77F. The fifteen minute pick ups felt good. I programed my Garmin with the workout so I was not getting accurate pacing. I thought I was going faster. Also, heart rate monitor kept sliding down secondary to the Chamois Butter. It is good to prevent chaffing but not good for holding up a chest strap. No I pushed each one to what I thought was a zone 3 pace. Realistically, it was probably slower than 9 min pace and my HR was higher than a zone 3 pace. After the third interval I was mush. It was like someone pulled the plug. Slower and slower. I was taking Infinit and had 8 endurlyes and 3 gels. Totals was 56oz fluid and 530mg/hr Na. Not the 800mg/hr I was hoping for. I felt like my legs were going to seize. The last 2 miles were walk/run slow. Very disappointing. Not sure if secondary to salt and hydration. Do not think it was glycogen issue. Next week I plan to weigh before and after. Aim higher for the salt intake and I ordered a new HR strap for my Garmin.
Sunday was a 1:30 bike ride for 23 miles with the focus just on rpms >80 in the big ring on back. The spin was good to clear out the lactic acid from Saturday's run. It was a sunny but pleasant day and very enjoyable. Nevertheless, I am nervous about my conditioning for the Marine corps marathon. I will run long next weekend and then the following weekend I will be visiting Addie at Emory so the mileage will be low.

  1. Way to go! It's been ridiculously hot here lately and still, you put out two good efforts. Hydration/sodium intake is something that I have struggled with as well. I guess it's par for the course when you live in Florida. During the summer months, I will take in about 35oz of liquid per hour during a run and right around 700-800mg/hr Na. Calories are about 150kcal/hr for a run and nearly 300kcal/hr for a long bike ride. I understand, however, that the amounts are all very personal... and sometimes taking in anything at all is easier said than done. Hopefully we'll have a cold snap in a few weeks and you'll be able to dial in your needs for MCM a bit better. :-) Have a great week!
