Did my first run of the year on saturday. Went faster than expected, did 9km in about 44 mins, various inclines/declines. Had my mate running with me though who runs all the time and he kept me going, I almost had to stop about 2/3rds of the way but kept going cause there was someone with me. Legs were very the next day, gonna do the same circuit backwards on saturday again, hopefully beat that time.
