First session of one minute reps. Fifteen of the delightful little sprints on the schedule. Started out a little rusty, but felt a whole lot lighter after one mile. This session is pretty tough on your own. Found it quite hard to push myself on the hills. Managed to set my Garmin to one minute alerts - and that was the main achievement of the day. Finished the 15 set feeling tired, but revitalised. Covered five miles in total.
