I've used pace wristbands and found them really helpful. Whenever I've attempted to follow a pacer I've found it very congested with other runners doing the same thing and I never found the pace quite suited me.It seemed that I was constantly adjusting my pace. But clearly many people like running with a pacer. If it were me in your position I would go for your sub 4 and hang on as long as you can. Be positive and believe in yourself.
I always find the taper in the last few weeks before a marathon a bit of a dilemma. Either I think I've tapered too much or too little. With less than 2 weeks now to race day what is the longest run people did as their longest run last week and what will your longest run be with one week to go? I did 14 on Sunday just gone but not sure what to do as my long run this coming Sunday, one week before the marathon. I'm always very wary of doing anything more than 8.
I'm due to run the Manchester Marathon. I am doing a 10k race two weeks before the marathon. I am an experienced runner and have done about twenty marathons but I've never done a race so close to a marathon before. I'd be interested to hear any views on this.Is it too close to be beneficial? Will it help me run faster in the marathon? Any experiences of running a short race close to running a marathon I'd be interested to hear about.
