Hi all, just signed up this morning. I'm fairly new to running, have been doing 5k once or twice a week, but just did the Glasgow Women's 10k last weekend in my best time yet of 63:51. I've signed up to do the half marathon in September and am needing to ramp up my training for this.
My main problem is that after the past 2 times I've been out (doing 5-6 miles) I've felt really sick after stopping. I also feel really cold, but this happens after any kind of running for me. Any advice to stop the sickness? Also, I usually get quite weary after around 3 miles, any tips for increasing endurance?
Thanks in advance.
