I was pacing the 90 minute group and really enjoyed it. Thanks to everyone I was running with for a great race. Will definitely be back next year to race it as that course could be seriously quick on the right day.
Highly recommend the Nectar gels Pete. Find they're a great mix between the SIS ones (way too watery) and some of the Shotz ones (basically gum). Gu are quite good as well. Always struggled but really get one with these ones.
Could easily be the energy gel/liquid (some of them are really hard work on the stomach). Only way to do it unfortunately is by experimenting each week with different combinations. Don't be scared to start off with a run without energy gels just make sure you have a decent breakfast and meal the night before.
You'll bonk about 17-18 miles so it'll be a struggle but it'll give you a good idea of whether the problem occurs all the time or just with gels and powdered liquid. Maybe take something for energy with you just in case.
